Performance comparison of turbo codes with LDPC codes and with BCH codes for forward error correcting codes

Abstract

In the field of communication, one of the most thriving and prevalent subject is the channel coding. Channel coding generally deals with the bandwidth which is the bit-rate or information storage capacity. It is a technical field which relies heavily on cost. In fact, it is undeniable that cost is the most crucial element in every system. Nowadays, together with the latency or time element which is also an equally significant factor, especially in mobile communication. The objective of this paper is to analyse and compare distinctively the three types of codes namely, turbo codes, LDBC codes and BCH codes, all simulated respectively in MATLAB environment. According to the conducted studies, it is evident that the BCH codes are excellent in performance compared to other codes. The turbo code, despite requiring maximum processing to decode the message has fairly good performance as well. Regardless of the level of processing, all the codes possess good & reliable performances compared to other codes.
