A Novel Approach of Digital Communication using 256QAM and Raised Cosine Filter

Abstract

Quadrature Amplitude Modulation (QAM) is a form of modulation which is generally used for modulating data signals onto a carrier used for digital communications. QAM, is probably preferred for advance communication as it holds higher data rate compared to traditional modulation scheme. This paper suggested a novel approach of digital communication using 256QAM modulation technique and raised cosine filter. Also, comparative analysis of the proposed model with state-of-art is reported in terms of Bit Error Rate (BER) and Symbol Error Rate (SER).
