Modulation enable us to transmit information at different frequencies. It plays a crucial role in transmit signals in communication systems. In this work, the performance of various modulation schemes under AWGN channel, Rayleigh fading channel and Rician fading channels are investigated. The performance comparison among PSK, OQPSK, PAM, QAM, DPSK, and MSK modulation is studied base on BERTool and the visual results shows that under the same transmission bandwidth and the same bit error probability, the QAM and MSK modulation has a better performance compared with other modulation method.
