ABSTRACT:
In a diversity receiver provided with diversity branches (51 and 52) which have a predetermined distance therebetween and each of which produces a received signal sequence in response to reception of a radio signal directed to the diversity receiver with a symbol rate, each of samplers (56 and 57) samples the received signal sequence with plural times of the symbol rate to produce a sampled serial signal sequence. Each of serial-to-conversion circuits (58 and 59) converts the sampled serial signal sequence into parallel signals. With reference to the parallel signals, channel impulse response estimation circuits (61 and 62, or 63 and 64) estimate channel impulse responses, respectively. In accordance with each of the estimated impulse response signals and each of the parallel signals, branch metric calculation circuits (66, 67, 68, and 69) calculate branch metrics. A branch metric combining circuit (71) combines the branch metrics into a combined branch metric. A Viterbi processor (72) carries out maximum likelihood sequence estimation in accordance with the combined branch metric.
