Combined Effect of Block interleaving and FEC on BER Performance of OFDM based WiMAX (IEEE 802.16d) System

WiMAX known as Worldwide Interoperability for Microwave Access is a wireless digital communications system designed to provide 30 to 40 megabit-per-second data rates, with the 2011 update providing up to 1 Gbit/s for fixed stations. It is also known as IEEE 802.16 that is intended for Wireless Metropolitan Area Networks (WMAN). WiMAX can provide broadband wireless access (BWA) typically 50 km for fixed stations, and 5 - 15 km for mobile stations. Whereas in contrast, the Wi-Fi/802.11 wireless local area network standard is limited in most cases to only 30 – 100 m. WiMAX is an IP based, wireless broadband access technology that provides performance similar to 802.11/Wi-Fi networks with the coverage and QOS (quality of service) of cellular networks. WiMAX can be used to provide a wireless alternative to cable and DSL for broadband access, and to provide high-speed data and telecommunications services.
