Abstract
The paper compares the performance of three techniques for providing tolerance to slow Rayleigh fading channels in cellular communication schemes: regular cyclic frequency hopping, adaptive modulation and coding, and dynamic carrier assignment (frequency jumping). 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 received power required, and in terms of the effects on overall system capacity. Various combinations of these schemes are also evaluated, and found to provide greater advantages.
