Abstract

The WIMAX technology based on air interface standard 802-16 wireless MAN is configured in the same way as a traditional cellular network with base stations using point to multipoint architecture to drive a service over a radius up to several kilometers. The range and the Non Line of Sight (NLOS) ability of WIMAX make the system very attractive for users, but there will be slightly higher BER at low SNR. In this paper, a comparison between the performance of wimax using convolutional code and convolutional product code (CPC) [1] is made. The CPC enables reducing BER at different SNR values compared to the convolutional code. For example, at BER equals 10-3 for 128 subcarriers, the amount of improvements in SNR is more than 2 dB. Several results are obtained at different modulating schemes (16QAM and 64QAM) and different numbers of sub-carriers (128 and 512).
