A VLSI Design for the LTE Turbo Decoder

Abstract

Due to the need of high performance, new wireless telecommunications standards such asWIMAX and LTE are using turbo-codes as a forward error correction (FEC) choice.This design targets either a self-contained IP (Intellectual Property) or integration into the physical layer project. This work presents all steps for the implementation of an LTE standard turbo decoder: from algorithm modeling in high level programming language to architecture using a sliding window approach seeking throughput needed, getting into physical implementation at TSMC 65nm. Each aspect of the specification and performance were analyzed in their proper stages.
