Abstract
This paper describes the implementation of a Viterbi decoder with a modified list-of-two List Output Viterbi Algorithm (LOVA) which is used to decode variable data rate frames in Code Division Multiple Access (CDMA) mobile stations. It performs the decoding of convolutional code k=9, rate=1/2 for fall, half, quarter, and eighth data rate frames. This Viterbi decoder is a part of a CDMA base-band processor used in an IS-95 cellular and Personal Communication System (PCS) mobile terminal.
