- The OFDM technique is predominantly used during the implementation of WiMAX Physical layer. This paper focuses on the PHY-layer design aspects, namely, modulation and coding techniques associated. OFDMA, an extension of OFDM, makes use of Adaptive Modulation and Coding techniques to improve efficiency, fairness, and throughput in WiMAX. To achieve higher data rates and smaller BER's channel coding can be carried out in OFDM, called COFDM. The channel state information is fed back to the transmitter by the channel estimator. The simulation analysis presented includes comparison of BER vs. SNR for different modulation schemes. Here, LMS channel estimator is used.
