Bandwidth efficient multilevel block 8-PSK modulation code for Rician fading channels

摘要

The degree of diversity and thereby the minimum Hamming distance (HD) of a code is known to be the most important design parameter in a perfectly interleaved nonfrequency-selective slowly-fading channel. The concatenation of an inner multilevel block modulation code with an outer nonbinary single parity check (SPC) code yields a doubling of the HD. Simulation results for Rayleigh and Rician fading channels show considerable coding gains compared to uncoded 4-PSK.
