Achieving Channel Capacity with Low Complexity RS-BTC Using QPSK over AWGN Channel

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 reliable transmission can be achieved at less than 1 d...

Zusammenfassung:	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 reliable transmission can be achieved at less than 1 dB from Shannon limit with very low complexity Reed-Solomon (RS) BTC under the same transmission condition. This is due to a proper choice of RS component codes used to construct RS product codes. Furthermore the size of the coded blocks required for RS-BTC to achieve a given code rate is much smaller than for BCH-BTC which is very attractive for practical considerations.
