Media and Radio Signal Processing for Mobile Communications Kyunghun Jung , Russell M Cambridge University Press 978-1-108-42103-4 — Media and Radio Signal Processing for Mobile Communications Kyunghun Jung , Russell M. Mersereau Frontmatter More Information Media and Radio Signal Processing for Mobile Communications Get to grips with the principles and practise of signal processing used in real mobile communications systems. Focusing particularly on speech and video processing, pion- eering experts employ a detailed, top-down analytical approach to outline the network architectures and protocol structures of multiple generations of mobile communications systems, identify the logical ranges where media and radio signal processing occur, and analyze the procedures for capturing, compressing, transmitting and presenting media. Chapters are uniquely structured to show the evolution of network architectures and technical elements between generations up to and including 5G, with an emphasis on maximizing service quality and network capacity through reusing existing infrastruc- ture and technologies. Examples and data taken from commercial networks provide an in-depth insight into the operation of a number of different systems, including GSM, cdma2000, W-CDMA, LTE, and LTE-A, making this a practical, hands-on guide for both practicing engineers and graduate students in wireless communications. Kyunghun Jung is a Principal Engineer at Samsung Electronics, where he leads the research and standardization for bringing immersive media services and vehicular applications to 5G systems. Russell M. Mersereau is Regents Professor Emeritus in the School of Electrical and Computer Engineering at the Georgia Institute of Technology, and a Fellow of the IEEE. © in this web service Cambridge University Press www.cambridge.org Cambridge University Press 978-1-108-42103-4 — Media and Radio Signal Processing for Mobile Communications Kyunghun Jung , Russell M. Mersereau Frontmatter More Information This impressive book provides an excellent comprehensive explanation of the principles and practices of media and radio signal processing in real mobile communications systems. It also wonderfully explains the evolution of signal processing operations and thereby gives the reader a deep insight into the challenges and how they were overcome. Kari Järvinen, Nokia Technologies With today’s mobile user experience so inuenced by multimedia services, providing a clear back- ground on the fundamentals of the entire protocol stack, from the physical layer to the multimedia codecs, media handling, and immersive media, is an invaluable book for understanding today’s mobile cellular systems. The authors’ experience with the development of the protocols and stan- dards of these systems provides unknown insights into the reason for their development that allows the reader to better understand these technologies.

Yoo Department of Electrical Engineering and Computer Science, Korea Advanced Institute of Science and Technology, Daejeon, Republic of Korea [email protected] Abstract as input. The length of each speech frame is 30 ms which cor- responds to 240 samples. Input speech of each frame is first In this paper, a novel transcoding algorithm for the Selectable high pass filtered and then divided into 4 subframes of 60 sam- Mode Vocoder (SMV) and the G.723.1 speech coder is pro- ples each. For every subframe, a 10th order linear prediction posed. In contrast to the conventional tandem transcoding al- coefficients (LPC) are computed. The linear predictive analysis gorithm, the proposed algorithm converts the parameters of one requires a look-ahead of 7.5 ms long. The LPC set for the last coder to the other without going through the decoding and en- subframe is quantized using the Predictive Split Vector Quan- coding process. The proposed algorithm is composed of four tizer (PSVQ) and transmitted. The unquantized LPC sets are parts: the parameter decoding, Line Spectral Pair (LSP) conver- used to obtain the perceptually weighted speech signal. For ev- sion, pitch period conversion and rate selection. The evaluation ery two subframes, the open-loop pitch analysis is performed in results show that the proposed algorithm achieves equivalent the domain of the weighted speech signal. Then, the adaptive speech quality to that of tandem transcoding with reduced com- codebook (ACB) and fixed codebook (FCB) are searched on a putational complexity and delay.

    Network Working Group R. Gellens Request for Comments: 4281 Qualcomm Category: Standards Track D. Singer Apple P. Frojdh Ericsson November 2005 The Codecs Parameter for "Bucket" Media Types Status of This Memo This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited. Copyright Notice Copyright (C) The Internet Society (2005). Abstract Several MIME type/subtype combinations exist that can contain different media formats. A receiving agent thus needs to examine the details of such media content to determine if the specific elements can be rendered given an available set of codecs. Especially when the end system has limited resources, or the connection to the end system has limited bandwidth, it would be helpful to know from the Content-Type alone if the content can be rendered. This document adds a new parameter, "codecs", to various type/subtype combinations to allow for unambiguous specification of the codecs indicated by the media formats contained within. By labeling content with the specific codecs indicated to render the contained media, receiving systems can determine if the codecs are supported by the end system, and if not, can take appropriate action (such as rejecting the content, sending notification of the situation, transcoding the content to a supported type, fetching and installing the required codecs, further inspection to determine if it will be sufficient to support a subset of the indicated codecs, etc.) Gellens, et al.

  • Wideband Speech Coding Standards and Applications
    Wideband Speech Coding Standards and Applications Abstract Increasing the bandwidth of sound signals from the telephone bandwidth of 200-3400 Hz to the wider bandwidth of 50-7000 Hz results in increased intelligibility and naturalness of speech and gives a feeling of transparent communication. The emerging end-to-end digital communication systems enable the use of wideband speech coding in a wide area of applications. Recognizing the need of high quality wideband speech codecs, several standardization activities have been recently conducted, resulting in the selection of a new wideband speech codec, AMR-WB, at bit rates from 6.6 to 23.85 kbit/s by both 3GPP and ITU-T. The adoption of AMR-WB by the two bodies is of significant importance since for the first time the same codec is adopted for wireless as well as wireline services. This will eliminate the need for transcoding, and ease the implementation of wideband voice applications and services across a wide range of communication systems and platforms. This document presents a summary of wideband speech coding standards for wideband telephony applications. The quality advantages and applications of wideband speech coding are first presented, and the issue of telephony over packet networks is discussed. Several wideband speech coding standards are discussed and a special emphasis is given to the AMR-WB standard recently selected by 3GPP and ITU-T. 1. Introduction Most speech coding systems in use today are based on telephone-bandwidth narrowband speech, nominally limited to about 200-3400 Hz and sampled at a rate of 8 kHz. This limitation built into the conventional telephone system dates back to the first transcontinental telephone service established between New-York and San Francisco in 1915.
