This paper presents a finite state machine based novel technique to model the Address Generation circuitry of WiMAX multimode interleaver using VHDL on FPGA platform with all code rates and modulation schemes of IEEE 802.16e standard.Abstract:Â
Wireless technology is the fastest growing segment of the modern communication industry. The IEEE 802.16e standard, commonly known as mobile WiMAX, is the latest wireless technology that has promised to offer Broadband Wireless Access over long distance. The concept of OFDM is used in WiMAX to obtain high data rate in addition to reducing the effects like inter symbol interference and inter channel interference. It has proved to be the air interface for next generation Broadband Wireless System. In this paper, we present a finite state machine based novel technique to model the Address Generation circuitry of WiMAX multimode interleaver using VHDL on FPGA platform with all code rates and modulation schemes of IEEE 802.16e standard. Our approach provides better performance in terms of maximum operating frequency, use of flip-flops with negligible loss in terms of logic cells utilized compared to existing FPGA based implementations. Measured circuit parameters and software simulation of this model are also provided.read more
