Abstract

In this paper, the performance of frequency hopping spread spectrum systems employing noncoherent reception and transmission diversity is analyzed for frequency selective Rayleigh fading (FSRF) channel.
Two different types of frequency diversity systems, fast frequency hopping (FFH) system and a multicarrier frequency hopping (MCFH) system are investigated. In order to combine received signal from transmit diversity channel, the optimum diversity-combining rule based on the maximum-likelihood criterion is described.
MCFH systems are found to outperform FFH systems when the channel delay spread ratio is severe at the same diversity order at low error rate. The optimum normalized frequency deviation for MCFH systems is found to increase with delay-spread ratio.
