CODED, DIVERSIFIED, RAYLEIGH-FADED BINARY SYMMETRIC THRESHOLD CHANNELS
Abstract
The expressions for the probabilities associated with a Rayleigh-faded channel with null-zone detecting and diversity used are derived. Quantitative results of machine computation are presented for different orders of diversity. The bounds of decoding error of a coding scheme designed for a null-zone channel are evaluated. Quantitative results are presented for various word lengths and transmission rates. The channel statistics are combined with the coding-error bounds, and an examination of the effective power gains and increases in reliability is carried out. A few hypothetical tropospheric scatter links are set up to investigate the practicality of the combination. A qualitative determination of the situation for which it appears feasible to combine null-zone detecting, diversity, and coding is given. (Author)
