Efficient Architecture for the Convolution Encoder and Viterbi Decoder for FPGA Implementation

Vinita Soni; Sandip Nemade

Error correcting codes (ECC) are one of the fundamental building blocks of an efficient communication system and utilization of proper encoding technique guarantees the error free communication in noisy environment although there are many types of ECC available the convolution codes are specifically preferred where the large constrain length are required with lower encoder complexity (like deep space communication). In this paper we are presenting an efficient design structure for the convolution encoder and decoder (Viterbi) for the FPGA implementation we also analyzed the developed mode for noisy situations for it correcting capabilities. The proposed model is synthesized and simulated using Xilinx ISE 14.4 software which shows that the proposed design effectively reduces the resource requirements and the power analysis on X-Power Analyzer shows considerable reduction in power requirements.
