The demand for high-speed mobile wireless communication is rapidly growing. Minimum Shift Keying (MSK) based modulation technology can be used for achieving high accuracy data transmission and for high data capacity. Phase Shift Keying (PSK) is used for MSK and Gaussian Minimum Shift Keying (GMSK). In this paper, we consider only MSK based signal and two channels; Additive White Gaussian Noise (AWGN) channel and Rician fading channel. MSK based modulated signals transmit through the AWGN channel with varying Signal to Noise Ratio (SNR) and signal power. Also MSK based modulated signals transmit through Rician fading channel with varying Doppler shift (fd) and the Rician K-factor. We analyze the properties of MSK based transmitted signal for each varying factors in both AWGN and Rician fading channel. A comparison has been made between the MSK based signal through AWGN and the MSK based signal through Rician fading channel. Finally, we investigate the BER performance of the MSK - based system for AWGN channel and Rician fading channel. Here, we propose that the AWGN channel is better than Rician fading channel for transmitting the MSK based modulated signal.
