Fourth-generation wireless communication system focus on two techniques which are, MIMO (Multiple Input and Multiple Output) and OFDM (Orthogonal Frequency Division Multiplexing) this paper demonstrates performance of BER of OFDM system using convolution code which used to encrypt the data stream that can be sent over communication channels, for different digital modulation schemes (8QAM, 16QAM, 32QAM and 64QAM) simulations in Matlab has been done for three different channels (AWGN , Racian and Rayleigh) , The obtained results show that 8QAM has good performance compared to other digital modulation schemes.
