PROJECT TITLE :

High Performance Reconfigurable Viterbi Decoder Design for Multi-Standard Receiver - 2016

ABSTRACT:

A Viterbi Decoder (VD) is employed to decode the convolutional codes, where convolutional codes are commonly used to encode digital information before transmission. However, there is a giant selection of modern wireless communication standards; a versatile hardware platform which will be configured to support completely different standards remains required. During this paper, a reconfigurable Viterbi decoder has been designed. The proposed Viterbi decoder has an design that supports constraint lengths three, 5, and seven, and code rates 1/a pair of and 1/three which makes it compatible with several common standards, like Wi-Max, WLAN, 3GPP2, GSM and LTE. The proposed Viterbi decoder has been simulated using Xilinx ISE fourteen.five simulator and implemented with VHDL on Xilinx Zed board, Zynq-7000 FPGA using Xilinx iMPACT device configuration tool. Moreover, in the proposed design design, a modified add-compare-select unit that efficiently reduces power consumption by 26percent and space by 21p.c is employed.
