In this paper, a new hybrid automatic repeat request (ARQ) scheme is proposed for data transmission in a powercontrolled direct sequence (DS) code division multiple access (CDMA) system cellular system. Data frame is composed of interleaved Reed-Solomon codes. The depth of interleaving is determined by a power-control interval. After decoding each codeword with algebraic decoding, the post-decoding processor decides whether to accept the codeword or to discard it by using channel state

... on from the power-control processor. The proposed hybrid ARQ scheme significantly reduces the probability of undetected error among accepted codewords without significantly reducing throughput.
