Performance analysis of channel aware frequency hopping

Abstract

An efficient method is presented to evaluate the performance of a channel-aware multiple-access scheme based on slow frequency hopping (CAFH) with r rounds. In contrast to conventional FH, which uses a channel state independent hopping sequence, the transmitter in the channel aware scheme hops to the available frequency subband which currently has the largest transmission gain. It is shown that this scheme can offer significant performance improvements over conventional FH at the cost of a more complex transmitter structure. The resulting closed-form expressions are used to investigate the effect of the number, r, of rounds on the error probability for a cellular communication system. Numerical examples are presented to illustrate the application of the new analysis.
