Abstract: The paper represents analysis Bit Error Rate (BER) performance of various modulation techniques. There are various modulation schemes such as Binary Phase Shit Keying (BPSK) and Quadrature Phase Shift Keying (QPSK). The performance in between these modulation techniques is analysed and best suited with respect to low Bit Error Rate (BER) is transmitted. Simulation is carried out on the software named MATLAB.
Keywords: OFDM, BPSK, QPSK, PSK, BER, SNR.
