Abstract
Diversity receiver structures are discussed in the context of a digital mobile radio system using time division multiple access (TDMA). Both selection diversity and combining diversity are considered. Simulation results are presented, with reference to the European GSM (Groupe Speciale Mobile) system, taking into account frequency selective Rayleigh fading and cochannel interference. Receiver structures and simulation results provide useful information for a performance/complexity tradeoff. It is shown that an estimate of signal quality, based on the TDMA preamble processing, can substantially improve the performances in any of the examined schemes, particularly in the interference-limited environment.Keywords
