The WiMAX forum is based on 802.16d/e Orthogonal Frequency Division Multiplexing (OFDM) based adaptive Physical Layer (PHY) layer. In this paper, the performance of WiMAX PHY layer is investigated for two PHY layer modifications, link adaption algorithm (Adaptive Modulation and coding, AMC) and MCCDMA (hybrid OFDM system with multiple access technology, Code Division Multiple Access) to provide high suppression against multipath fading , provide high bandwidth efficiency, high throughput with high data rates for mobile environments. The results obtained for these modifications show that these mechanisms enhance the performance of the PHY layer in mobile environments with lower BER and high spectral efficiency.
