摘要：The Worldwide Interoperability for Microwave Access (WiMAX) is currently one of the hottesttechnologies in wireless. The Institute of Electrical and Electronics Engineers (IEEE) 802 committee, which setsnetworking standards such as Ethernet (802.3) and WiFi (802.11), has published a set of standards that define WiMAX.IEEE 802.16-2004. These operate in the 2.5GHz, 3.5GHz and 5.8 GHz frequency bands. WiMAX, is based on an RFtechnology called Orthogonal Frequency Division Multiplexing (OFDM), which is a very effective means oftransferring data when carriers of width of 5MHz or greater can be used. WiMAX is a standard-based wirelesstechnology that provides high throughput broadband connections over long distance. WiMAX can be used for anumber of applications, including ―last mile‖ broadband connections, hotspots and high-speed connectivity for businesscustomers.This work proposes an algorithm on address generation circuitry of Deinterleaver using QPSK and 16 QAMmodulations for WiMAX transceiver. The floor function associated with the implementation of FPGA is very difficultin IEEE 802.16e standard. The requirement of floor function can be eliminated by using a simple mathematicalalgorithm. The main aim of the work is to concentrate on performance improvement by reducing interconnection delay,lesser power consumption, and efficient resource utilization by comparing with prevailing technique. This work focuseson removing the complexities and excess hardware involvement in the implementation of the permutations involved inDeinterleaver designs as defined by IEEE 802.16.
