Adaptive redundant residue number system coded multicarrier modulation

The novel class of nonbinary maximum minimum distance redundant residue num ber system (RRNS) codes is invoked in the context of adaptively RRNS coded, symbol-by-symbol adaptive multicarrier modulation, in order to combat the effects of frequency-selective fading inflicted by dispersive wide-band cha nnels. The system's performance can be adjusted in order to maintain a give n target bit error rate (BER) and bit per symbol (BPS) performance. The pro posed adaptive RRNS scheme outperforms the convolutional constituent code b ased turbo coded benchmarker system for channel signal-to-noise ratios (SNR ) in excess of about 15 dB at a target BER of 10(-4).
