Ordered statistics decoding of linear block codes on the WSSUS multipath channel
The ordered statistics decoding algorithm is applied to the wide-sense-stationary uncorrelated-scattering (WSSUS) Rayleigh fading channel, modeled as a frequency non-selective, slow-fading environment without intersymbol interference (ISI). We derive the log-likelihood ratio of received symbols based on 2-DPSK transmission. Simulations are conducted for the WSSUS channel at various interleaving degrees. At bit error rate (BER) of 10/sup -5/ and 38 dB gain compared to uncoded 2-DPSK are obtained for the decoding of the (128,64,22) extended BCH code with interleaving degree 50.
