Reconfigurable Adaptive Viterbi Algorithm for Conventional Decoding

Glory Priscilla N, Ramesh Patnaik M.

Abstract


Conventional encoder is widely applied to lots of wireless communications including 3G/4G communication and digital video Broad casting (DVB), IOT (Internet of things) transmission and so on. A reconfigurable Viterbi decoder design is proposed for LTE-A, WiMAX, LTECDMA, GSM and TD-SCDMA. The proposed flexible architecture supports a polynomial reconfiguration. More over both tail biting and zero trellis terminating modes are supported. The transmitter encoder and receiver decoder are designed for verifying functionality .The purpose is to determine the feasible to design data error correcting to reduce the decoding latency and complexity it employs forward trace back method and sliding window technology.
