Compressive Sensing for the Capacity of a Rayleigh Fading Channel
2011 IEEE International Conference on Communications (ICC), 2011A given objective function, $I(p_X(x))$, is to be maximized over the argument $p_X(x)$, where $p_X(x)$ is a continuous function of $x \in R^1$. Rather than optimizing $I(p_X(x))$ over the domain of functions, where the optimal solution $p_X^*(x)$ is non-zero only at a few but unknown discrete points $x \in \{x_1 , x_2 , \ldots , x_S \} $, is it ...

Optimized Selection Diversity for Rayleigh Fading Channels
IEEE Transactions on Communications, 1982This paper considers the choice of the number of diversity branches for minimizing the bit error rate of a selection diversity system using noncoherent binary frequency-shift keying modulation for transmission over a Rayleigh fading Gaussian channel. An exact expression for the optimum number of branches, L_{sel}^{\ast} , is given.

LDPC coded modulation for Rayleigh fading channels
2012 International Conference on Wireless Communications and Signal Processing (WCSP), 2012This paper presents a novel scheme of low-density-parity-check (LDPC) coded modulation system called bit-expand-interleaved coded modulation with iterative decoding and demapping (BEICM-ID) over Rayleigh fading channels. In traditional bit-interleaved coded modulation (BICM) schemes and its iterative version, BICM-ID, each bit node is mapped into one ...

Wireless QoS analysis for a Rayleigh fading channel
ICC '98. 1998 IEEE International Conference on Communications. Conference Record. Affiliated with SUPERCOMM'98 (Cat. No.98CH36220), 2002We present an analysis of the relationship between the two link-level QoS (quality of service) parameters (delay and error rate) and the motion speed of a user in a wireless packet network environment. The analysis is based on: (1) a wireless channel simulation using a time-correlated Rayleigh fading model and (2) a physical layer model which complies ...

On the capacity of CPM over Rayleigh fading channels
2012 International Conference on Wireless Communications and Signal Processing (WCSP), 2012In this paper, an algorithm is proposed to calculate the capacity of continuous phase modulation (CPM) over Rayleigh fading channels. The proposed algorithm is an extension of the simulation-based algorithm for calculating information rates of channels with memory. We modify the algorithm by taking into account the fading coefficients.

Multilevel block codes for Rayleigh-fading channels
IEEE Transactions on Communications, 1995Summary: New multilevel block codes for Rayleigh-fading channels are presented. At high signal-to-noise ratios, the proposed block codes can achieve better bit error performance over TCM codes, optimum for fading channels, with comparable decoder complexity and bandwidth efficiency.

Prediction of State Transitions in Rayleigh Fading Channels
IEEE Transactions on Vehicular Technology, 2007This paper presents a channel-sampling scheme that allows robust estimation of channel transitions into and out of the fade state. The sampling scheme is based upon a second-order autoregressive (AR-2) model for the Rayleigh fading channel and a corresponding state-space representation in terms of fade and nonfade states.

Co-channel interference reduction in Rayleigh fading channels
Digital Signal Processing, 2006Abstract Interference can be a significant problem in loosely organized networks such as ad-hoc radio networks. One technique for dealing with interference is to attempt joint detection of all signals arriving at a node. Iterative algorithms based on the turbo-principle yield significant performance improvements when applied to this problem.

Decoding of constellations matched to the Rayleigh fading channel
Annales Des Télécommunications, 1998Il a ete recemment montre que l’utilisation de constellations a d dimensions specialisees pour le canal de Rayleigh permettait d’obtenir une diversite d’ordre d sans aucun codage (constellation π) [6–8]. Cependant, le decodage de ces constellations est tres complexe et rend problematique leur utilisation dans des applications haut debit.

Secrecy capacity of correlated rayleigh fading channels
2012 18th Asia-Pacific Conference on Communications (APCC), 2012We consider the secure transmission of information over Rayleigh fading wiretap channel when the main and eavesdropper channels are correlated there. Assuming that before transmission the transmitter knows the full channel state information (CSI) of both the main and eavesdropper channels, we analyze the average secrecy capacity with limited signal-to ...
