  • Efficient Multi-Carrier Communication on the Digital Subscriber Loop
    Efficient Multi-Carrier Communication on the Digital Subscriber Loop Donnacha Daly Department of Electrical and Electronic Engineering Faculty of Engineering and Architecture University College Dublin National University of Ireland A thesis presented to the National University of Ireland Faculty of Engineering and Architecture in fulfillment of the requirements for the degree of Doctor of Philosophy May 2003 Research Supervisors: Dr. C. Heneghan Prof. A. D. Fagan Head of Department: Prof. T. Brazil Abstract This thesis explores three distinct philosophies for improving the efficiency of multi-carrier com- munication on the digital subscriber loop. The first topic discussed is impulse response shortening for discrete multitone transceivers. The minimum mean-squared error impulse response shortener is reformulated to allow near-optimal rate performance. It is demonstrated that the best existing eigen-filter designed channel shortener is a particular case of the proposed reformulation. An adap- tive time-domain LMS algorithm is provided as an alternative to eigen-decomposition. The next part of the thesis examines bit- and power- loading algorithms for multitone systems. The problem of rate-optimal loading has already been solved. It is shown, however, that the rate-optimal solu- tion does not give best value for complexity, and that near optimal schemes can perform very well at a fraction of the computational cost. The final section of the thesis is a brief exposition of the use of wavelet packets to achieve multi-carrier communication. It is proposed that the non-uniform spectral decomposition afforded by wavelet packet modulation allows reduced inter-symbol inter- ference effects in a dispersive channel.

I know that these conferences have served as a sounding board for technical ideas. Some have become standards and accepted by the mainstream. Amateur packet radio is certainly an example of amateurs contributing to the state-of-the-art. The League is now faced with increasing difficulty justifying our precious spectrum. It doesn’t at all reflect poorly on amateurs. The problem is that commercial services are seeking spectrum, on a shared basis if necessary, when they can’t get exclusive allocations. If you’d asked me earlier this year if extensive amateur use of a band would protect it against encroachment, I would have said “yes.” You will remember the saying, “Use it or lose it.” Well, we certainly can lose a band by not using it.

Brief Description The CMX865A is a multi-standard modem for use in Wireless Local Loop, Short Message Service telephone based information and telemetry systems. Flexible line driver, hybrid and receiver circuits are integrated on chip, requiring only passive external components to build a 2 or 4-wire line interface. A high-quality DTMF decoder with excellent immunity to falsing on voice and a standard DTMF encoder are included. Alternatively, these blocks can be used to transmit and detect user-specific, programmed single and dual-tone signals, simple melodies, call progress signals or modem calling and answering tones. Host control and data transfer is via a high-speed serial bus that operates in normal and Powersave modes and which is compatible with most simple types of µC serial interface. An embedded USART allows multi-format asynchronous data and unformatted synchronous data to be received or transmitted as 8-bit bytes. The CMX865A operates from a single 3.0V to 3.6V supply over a temperature range of -40°C to +85°C and is available in 16-pin SOIC (D4) and 16-pin TSSOP (E4) packages.
