Efficient Recovery of Data In Digital Communication Using FPGA
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2013, Vol 2, Issue 8
Abstract
Survey on reduction in error by special encoding and decoding technique using FPGA that is by using convolutional encoding and viterbi decoding. Forward error correction (FEC) is one of the key parts of any digital communication system (especially system that sends the information in a noisy environment) for the reliable data transfer. FEC requires only one way link, and its parity bits target both error detection and correction. The purpose of FEC communication scheme is to add redundancy to the transmitted data so that any errors introduced by the communication channel can be corrected by the receiver. Convolutional encoding with the viterbi decoding is one of the most popular and excellent error correction techniques for correcting random errors. It is one of the most widely used FEC methods in many digital communication systems. In this case the convolutional encoding and viterbi decoding is by using FPGA with variable input bit lengths (as 7, 8 and 9) is shown using the special simulation modules with XILINX software.
