WLAN plays an important role as a complement to the existing or planned cellular networks which can offer high speed voice, video and data service up to the customer end. The aim of this paper is to analysis the performance of coded WLAN system for different digital modulation schemes (BPSK, 16-PSK, QPSK, 4-QAM and 16-QAM) under AWGN channel. The performance of convolution encoder WLAN system is in terms of graph between BER and SNR. We also verify the system performance with different code rates (1/2, 1/3, 2/3 1nd 3/4) and different constraint length.
