A Review: BER Performance Analysis of Linear Block codes used in FEC over AWGN channel

Abstract

Nowadays, in modern data transmission communication system forward error correction (FEC) codes are
widely used for error detection and correction mechanisms. Linear Block codes such as Bose-Chaudhuri-Hocquenghem
(BCH), Hamming, Cyclic Redundancy Check (CRC), Reed-Solomon (RS) codes are used as FEC and calculate bit error
rate of the system (BER). In this paper, we reviews and analysis the BER performance of these Linear Block codes at
same block length of (255, 247) over Additive White Gaussian Noise (AWGN) channel using Binary Phase-shift keying
(BPSK) modulation. In addition, while comparing BER performance, we selected lower SNR values from 0 to 9 and
analyzed that BCH code gives slightly better results than RS, Hamming and CRC-16 codes. While selecting high SNR
values from 0 to 18, the RS code gives better BER performance than BCH, Hamming and CRC-16 codes. The whole
simulation process for coding and decoding of Linear Block codes in this paper work is performed using MATLAB
software.
