The Design and Implementation of a General Purpose and High Speed Viterbi Decoder in CDMA2000 System
This paper describes the FPGA design of a general purpose and high speed Viterbi decoder which can be used in cdma2000 mobile communication system. This decoder can decode data with varible code rate and frame length. Meanwhile ,this decoder reaches high speed to 588 kbit/s by taking 4ACS parallel structure.This Viterbi decoder can be used in 3G mobile communication sysetmes and other systems.
