In this paper, the authors simulate and evaluate the performance of physical layer of wireless communication system of CDMA-2000 specification using radio configuration-3 under forward fundamental channel 1x in terms of Bit Error Rate (BER) by using convolution code. They modeled and evaluated convolution encoder at different rates ?,1/3,1/4 using constraint length k of 3,4,5,6,7,8,9,10 values, under different noise channels (AWGN, BSC, Rayleigh. Rician, combination of AWGN and Rayleigh, combination of AWGN and Rician channel). On the basis of better simulated results of convolution encoder at rate ? and higher constraint length in all noise channel, they simulated rate ? convolution encoder with constraint length (k) 9 and structure [775 631 413 471] in CDMA-2000 physical layer.
