Analysis of modulation and coding scheme for 5th generation wireless communication system

Abstract

Advancing in communication technology, 5th Generation Wireless Communication System is playing a significant role. The 5th Generation wireless communication system involves different types of coding and modulation schemes for the better performances and efficient outputs. This paper analyzes the different coding schemes and modulation techniques and compares between them. The performances have been compared between the Turbo and Viterbi Coding Schemes. And the modulation techniques have been compared between QPSK and QAM modulation techniques. The QAM modulation scheme will be used for the users closer to the BTS (Base Transceiver Station). And QPSK modulation technique will be used for the users closer to the border of the cells. For both of the modulation techniques, both the coding schemes have been used and performances have been compared. Finally for all the modulation schemes, Viterbi Coding techniques (Convolutional Encoding and Viterbi Decoding) have proved its efficient performances in use.
