Comparative Performance Analysis of Digital Modulation Schemes with Digital Audio Transmission through AWGN Channel
With the dawn of internet and smart phones, modern communication systems have consistently evolved as they became more advanced and sophisticated and less prone to distortions. This paper analyses the different digital modulation techniques employed during transmission of signal via Additive White Gaussian Noise (AWGN) channel. Comparative analysis is carried out in case of M-ary Phase Shift Modulation (MPSK) techniques viz. BPSK, QPSK, 8-PSK and 16-PSK and consequently their Bit Error Rates (BER) are analyzed. Furthermore, a standard audio signal is passed through AWGN channel while employing these M-ary Phase Shift Modulation (MPSK) techniques and result is analyzed. In the next part, a real time speech signal is transmitted and passed through AWGN channel where BPSK and QPSK are deployed and the results are analyzed.
