V. B. Malode, B. P. Patil . Performance of Linear Block Coded OFDM System in BER and PAPR under Different Channels. International Journal of Applied Information Systems. 3, 4 ( July 2012), 6-12. DOI=10.5120/ijais12-450503
Orthogonal Frequency Division Multiplexing (OFDM) plays a prominent role in wireless communication technology as multicarrier transmission scheme. The IEEE 802. 11a standard uses coded OFDM scheme. This paper is to evaluate the performance of Coded OFDM system in different channels. Linear Block Code (LBC) with Extended Hamming is used to check the improvement of the system performance in BER (bit error rate). The results are obtained for different channels Like Additive White Gaussion Noise (AWGN), Rayleigh and Rician. The DQPSK modulation is used for scheme are comparison purpose. The Differential detection technique is used to avoid the need of a complex equalization process. PAPR for QPSK and DQPSK with conventional and SLM is computed for the comparison purpose.
