BER performance of M-ary FSK modulation over AWGN and Rayleigh fading channels

Abstract EN

In a mobile communication environment, there is a rising demand of low Bit Error Rate (BER).

The channel is not time invariant since the received signal depends on many fast changing factors, and thus it will lead to fading channels.

Statistical models are typically used to simulate fading.

In this paper, the BER versus Eb/No will simulate the non-faded and faded channels.

Using Rayleigh statistical model, the BER of different channel fading types is studied based on time delay spread can have flat fading or frequency selective fading and also based on the Doppler shift can have slow fading or fast fading taking into consideration the M-ary FSK modulation scheme.

The overall system is implemented by using MATLAB.
