MAP Detection and Robust Lossy Coding Over Soft-Decision Correlated Fading Channels

Robust Lossy Source Coding for Correlated Fading Channels

Most of the conventional communication systems use channel interleaving as well as hard decision decoding in their designs, which lead to discarding channel memory and soft-decision information. This simplification is usually done since the complexity of handling the memory or soft-decision information is rather high. In this work, we design two lossy joint source-channel coding (JSCC) schemes ...

Robust Spa e-Time Coding for Correlated Rayleigh Fading Channels

Turbo Coding in Correlated Fading Channels

Turbo Code research has primarily focused on applying the codes to Additive White Gaussian Noise (AWGN) channels, and to Rayleigh fading channels where the fading parameter was fixed over the duration of a symbol. Turbo Coding has reached within 1dB of the Shannon limit in AWGN channels, and within 2dB of the Shannon limit in slow fading Rayleigh channels. However, in mobile radio a primary app...

Random Beamforming over Correlated Fading Channels

We study a multiple-input multiple-output (MIMO) multiple access channel (MAC) from several multi-antenna transmitters to a multi-antenna receiver. The fading channels between the transmitters and the receiver are modeled by random matrices, composed of independent column vectors with zero mean and different covariance matrices. Each transmitter is assumed to send multiple data streams with a r...

Error control mechanisms over correlated fading channels

This paper considers the application of Forward Error Correction (FEC) and Automatic Repeat reQuest (ARQ) schemes over correlated wireless channels. In particular the depth of the interleaver and its influence on the frame-error-rate and transmission delay in the presence of Correlated fading and delay constraints is investigated. It is found that an increased interleaver depth in a correlated ...
