Reduced complexity diversity combining and adaptive equalization using interpolated channel estimates with applications to cellular mobile radio channels

摘要

We investigate an antenna diversity combiner-equalizer receiver structure to combat multipath fading in cellular mobile radio (CMR) communications. Our system specifications are compatible with the US digital cellular system. The technique utilizes block adaptation and linear or decision feedback equalization. The receiver offers complexity reduction relative to previously proposed block adaptation methods without sacrificing the system's performance.
