Potential applications of low complexity non-binary high code rate block turbo codes

High code rate block turbo codes (BTC) using Bose-Chaudhuri-Hocquenghem (BCH) codes have already demonstrated near Shannon performances for quadrature phase-shift keying (QPSK) over additive white Gaussian noise (AWGN) channel. We show here that very low complexity Reed-Solomon (RS) BTC can also achieve reliable transmission at less than 1 dB from Shannon limit with the same transmission conditions. Performances of this RS-BTC over binary symmetric channel (BSC) and binary erasure channel (BEC) are also investigated in this paper. Potential applications for this study are high speed optical transmission and data storage.
