Since these progressive transmissions have gradual differences of importance in their bitstreams, which can benefit differences of importance in their bitstreams, a large number from multiple levels of unequal error protection (UEP). Though of error protection levels are required. However, hierarchical hierarchical modulation has been intensively studied as an UEP approach for digital broadcasting and multimedia transmission, modulation can achieve only a limited number of UEP levels methods of achieving a large number of UEP levels have rarely for a given constellation size.

In this paper, we propose a multilevel UEP system QAM provides two levels of UEP, and hierarchical 64 QAM using multiplexed hierarchical quadrature amplitude modulation yields at most three levels [11].

    1 Generic Approach for Hierarchical Modulation Performance Analysis: Application to DVB-SH and DVB-S2 Hugo Meric´ ∗y,Jer´ omeˆ Lacany∗, Caroline Amiot-Bazilez, Fabrice Arnalx and Marie-Laure Boucherety∗ ∗TeSA,´ Toulouse, France yUniversite´ de Toulouse, Toulouse, France zCNES, Toulouse, France xThales Alenia Space, Toulouse, France Email: [email protected], [email protected], [email protected], [email protected], [email protected] Abstract Broadcasting systems have to deal with channel variability in order to offer the best rate to the users. Hierarchical modulation is a practical solution to provide different rates to the receivers in function of the channel quality. Unfortunately, the performance evaluation of such modulations requires time consuming simulations. We propose in this paper a novel approach based on the channel capacity to avoid these simulations. The method allows to study the performance of hierarchical and also classical modulations combined with error correcting codes. We will also compare hierarchical modulation with time sharing strategy in terms of achievable rates and indisponibility. Our work will be applied to the DVB-SH and DVB-S2 standards, which both consider hierarchical modulation as an optional feature. arXiv:1103.1742v1 [cs.IT] 9 Mar 2011 Index Terms Hierarchical Modulation, Channel Capacity, Digital Video Broadcasting, System Performance. I. INTRODUCTION In most broadcast applications, all the receivers do not experience the same signal-to-noise ratio (SNR). For instance, in satellite communications the channel quality decreases with the presence of clouds in Ku or Ka band, or with shadowing effects of the environment in lower bands. The material in this paper will be presented in part at WTS 2011, New-York, United States, April 2011.

  • Digital Domain Power Division Multiplexed Dual Polarization

As the backbone infrastructure of modern communication networks, the optical fber transmission system undergoes a signifcant capacity growth over decades by exploiting available physical dimensions (time, frequency, quadrature, polarization and space) of the optical carrier for multiplexing. For each dimension, stringent orthogonality must be guaranteed for perfect separation of independent multiplexed signals. To catch up with the ever-increasing capacity requirement, it is therefore interesting and important to develop new multiplexing methodologies relaxing the orthogonal constraint thus achieving better spectral efciency and more fexibility of frequency reuse. Inspired by the idea of non-orthogonal multiple access (NOMA) scheme, here we propose a digital domain power division multiplexed (PDM) transmission technology which is fully compatible with current dual polarization (DP) coherent optical communication system. The coherent optical orthogonal frequency division multiplexing (CO-OFDM) modulation has been employed owing to its great superiority on high spectral efciency, fexible coding, ease of channel estimation and robustness against fber dispersion. And a PDM-DP-CO-OFDM system has been theoretically and experimentally demonstrated with 100 Gb/s wavelength division multiplexing (WDM) transmission over 1440 km standard single mode fbers (SSMFs). To meet the increasing demand of high capacity optical fber transmission network, fve available physical dimen- sions including time, frequency, quadrature, polarization and space have been utilized for modulation and multi- plexing in optical communications1.

  • Transmitter Authentication Using Hierarchical Modulation in Dynamic Spectrum Sharing$
    Transmitter Authentication Using Hierarchical Modulation in Dynamic Spectrum SharingI Vireshwar Kumara,∗, Jung-Min (Jerry) Parka, Kaigui Bianb aDepartment of Electrical and Computer Engineering, Virginia Tech, Blacksburg, Virginia, 24061, USA bSchool of Electronics Engineering and Computer Science, Peking University, Beijing, 100871, China Abstract One of the critical challenges in dynamic spectrum sharing (DSS) is identify- ing non-conforming transmitters that violate spectrum access rules prescribed by a spectrum regulatory authority. One approach for facilitating identifica- tion of the transmitters in DSS is to require every transmitter to embed an uniquely-identifiable authentication signal in its waveform at the PHY-layer. In most of the existing PHY-layer authentication schemes, the authentication signal is added to the message signal as noise, which leads to a tradeoff be- tween the message signal's signal-to-noise ratio (SNR) and the authentication signal's SNR under the assumption of constant average transmitted power. This implies that one cannot improve the former without sacrificing the latter, and vice versa. In this paper, we propose a novel PHY-layer authentication scheme called Hierarchical Modulation with Modified Duobinary Signaling for Authenti- cation (HMM-DSA), which relaxes the constraint on the aforementioned trade- off. HMM-DSA utilizes a modified duobinary filter to introduce some controlled amount of inter-symbol interference into the message signal, and embeds the au- thentication signal in the form of filter coefficients. Our results show that the proposed scheme, HMM-DSA, improves the error performance of the message signal as compared to the prior art.
