Joint-Detection and Interference Cancellation Based Burst-by-Burst Adaptive CDMA Schemes

open access: yes, 2002
Spread adaptive quadrature amplitude modulated (AQAM) code-division multiple access (CDMA) is proposed as a powerful means of exploiting the time-variant channel capacity fluctuations of wireless channels.

A Turbo-Detection Aided Serially Concatenated MPEG-4/TCM Videophone Transceiver

open access: yes, 2004
A Turbo-detection aided serially concatenated inner Trellis Coded Modulation (TCM) scheme is combined with four different outer codes, namely with a Reversible Variable Length Code (RVLC), a Non-Systematic Convolutional (NSC) code a Recursive Systematic ...

Jointly optimised iterative source-coding, channel-coding and modulation for transmission over wireless channels

open access: yes, 2004
Joint source-coding, channel-coding and modulation schemes based on Variable Length Codes (VLCs), Trellis Coded Modulation (TCM), Turbo TCM (TTCM), Bit-Interleaved Coded Modulation (BICM) and iteratively decoded BICM (BICM-ID) schemes are proposed.

On the Computation of EXIT Characteristics for Symbol-Based Iterative Decoding

open access: yes, 2006
In this paper we propose an efficient method for computing index-based extrinsic information transfer (EXIT) charts, which are useful for estimating the convergence properties of non-binary iterative decoding.
