Comparison of counter-measures against slow Rayleigh fading for TDMA systems

This paper compares the performance of three techniques for introducing tolerance to slow Rayleigh fading channels for TDMA fixed radio access schemes within a single cell: regular cyclic frequency hopping, adaptive modulation and coding, and frequency jumping when required. It is assumed for the channels considered that the fading rates are slow enough that simple feedback adaptive techniques are applicable. The theoretical maximum performance of each scheme is evaluated as a function of the number of conversations supportable and the average transmitted power required
