Abstract

This paper investigates the performance of ordered statistics decoding of linear block codes with binary differential phase-shift-keying (2DPSK) transmission on the wide-sense-stationary uncorrelated-scattering (WSSUS) Rayleigh fading channel. For a typical mobile speed of 60 mph, tropospheric scatter radio communication at a carrier frequency of 900 MHz and very low bit rate video communication at a transmission speed of 32 kbit/s, the channel is modeled as a frequency non-selective, slow fading environment without inter-symbol interference (ISI). At a bit error rate (BER) of 10^-5, 34.5 dB and 38 dB gains compared to uncoded 2DPSK are obtained for the decoding of the (24,12,8) extended Golay code and the (128,64,22) extended BCH code with sufficient degree of interleaving
