BER ANALYSIS of CHANNEL CODING TECHNIQUES for 5G NETWORKS

Abstract

All Achieving error free communication is the major challenge in wireless technology because it provides the basement for reliable communication. But, practically error free communication is not possible due to impairments caused in wireless channel. The practical option that is available for reliable communication with minimized error rate is a channel coding technique. The various channel encoding techniques used are RS, convolutional codes, turbo codes etc., in various generations of wireless communication. The advanced version of 5G technologies needs a new type of channel coding technique that focuses on low complexity and minimized bit error rate. In this system candidate error correction coding schemes that can be used for 5G technology is reviewed in terms of bit error rate and complexity. This proposed system mainly focuses on two channel coding techniques namely convolutional codes and LDPC codes. The LDPC codes are currently used in 4G technologies and its feasibility with 5G wireless communication is evaluated in terms of BER performance and complexity and it is compared with the coded and uncoded convolutional codes. The results show that LDPC codes outperform the other coded system in terms of BER and complexity, also channel capacity of the MIMO-OFDM system is achieved nearer to the Shannon limit by using LDPC codes. According to the conducted studies, it is evident that the LDPC codes are excellent in having improved BER performance such that it could be used for next generation wireless communication.
