Abstract

In mobile radio communications, antenna arrays can be used to improve the quality and/or the capacity of the communication system. The combination of an antenna array and maximum likelihood sequence detection (MLSE) is studied. Different realizations of the multi-channel MLSE are presented. Although equivalent in performance, it is pointed out that one of them, the multi-dimensional matched filter approach, is superior in terms of computational complexity when more than one antenna is used. For completeness, temporally colored noise is included in the formalism
