Summary:In mobile communications, the receiver must mitigate severe signal impairments arising from multipath and Rayleigh fading. Multipath produces intersymbol interference (ISI), necessitating the use of an equalizer in the receiver. The performance of the equalizer can be significantly improved using antenna diversity, thereby allowing the use of lower C/I values. This C/I reduction offers potential for capacity enhancement. This paper describes the use of pre-detection antenna diversity in conjunction with a MLSE receiver for the U.S. Digital Cellular (USDC) system. It is shown that the receiver meets all the USDC (IS-54) performance specifications with a significant margin and has a computational complexity of less than 4 MIPS.< >
