| Abstract: | This paper describes the design and implementation of a general-purpose and high speed Viterbi decoder which can be used in the third generation mobile communication systems.This decoder can decode the soft data stream with variable code rate and frame length,thus is generalurpose in a sense.Meanwhile,this decoder reaches the high speed decoding rate up to 588kbps by taking the double-pipeline parallel structure.This Viterbi decoder is so general-purpose and portable that it can be used in many systems especially in the third generation mobile communication systems. |
