Combined coding-diversity (CCD) schemes for fading channels

Abstract

To combat the effect of performance degradation due to the multipath fading, diversity techniques are known as the most advantageous procedure without increasing either the transmitted power or the bandwidth requirement. Combination of the coding, which is used for power-limited and band-limited channels, and diversity is a new aspect to exploit both for such channels as mobile radio. Some new combined coding-diversity (CCD) schemes are introduced, and simulated over uncorrelated Rayleigh fading which trellis detection and decoding simultaneously have been used.
