IEEE 802.16d/e PHY layer adapted by WiMax forum includes multiple specifications, which make the standard flexible and adaptable to different frequency ranges. The PHY layer specifies some mandatory features and some optional features to be implemented to provide a reliable end-to-end link. The primary issue in implementation of PHY layer is robust performance in multipath fading environments. In this paper, the performance of WiMax PHY layer with turbo coding mechanisms is investigated and compared with the existing mechanisms. The results obtained show that turbo coding offers lower BER and enhance the performance of the PHY layer in mobile (multipath) environments.
