Abstract

A type-1 hybrid automatic-repeat-request (ARQ) scheme with time diversity combining is proposed and its performance is analyzed for binary digital FM digital mobile radio communication. Diversity combining is achieved by exploiting the packet retransmission nature inherent in the ARQ scheme. The ARQ scheme uses a high rate error-correcting code with soft-decision decoding. Received signal envelopes are sampled and used as channel state information in the decoding process. Numerical results on the system throughput and decoded bit error rate (BER) are presented as functions of average information signal-to-noise ratio, average information signal-to-interference ratio, and random FM noise
