Abstract

This study focuses on three basic digital modulation techniques ASK, FSK, and PSK. The conveyed signals of these modulation techniques are defined by a distinct system of values appearing at gradually separated times. The bandwidth efficiency and easy implementation are important factors in deciding which digital modulation method to use for a given application, but so are the bit error rate BER and signal to noise ratio. Binary modulation systems employ two values, are simple to implement, give adequate error substantiation. The bit error rate BER is an important statistic for evaluating systems that transmit signal data from one location to another. The SNR is a well known metric for comparing signal and noise power. It has a direct impact on a systems chance of bit error rate. Authors used MATLAB to construct BPSK, QPSK, QAM in this paper. As a carrier wave, the cosine signal was used. The analysis is carried out with SNR over AWGN channel as the reference factor in this work, which proposes a comprehensive examination of BER performance of QPSK, BPSK, QAM for channel usage.
