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 BPSK under AWGN channel. The Low-Density Parity-Check (LDPC) coding is considered as the high-performance channel coding scheme due to its good trade off between performance and complexity. The performance of LDPC (Low Density Parity Check matrix code) encoder WLAN system is in terms of graph between BER and SNR. The authors also verify the system performance with different code rates and different parity check matrix.
