Concatenated codes using multilevel structures for PSK signalling over the Rayleigh fading channel

摘要

The authors investigate the application of concatenated codes to the Rayleigh fading channel using M-PSK modulation. To obtain a variety of diversity levels, the authors propose several concatenated schemes where the inner codes are multilevel codes. This approach yields high diversity with low complexity, essentially providing soft decision decoding performance on Reed-Solomon codes.
