Implementation of OFDM Baseband Trasmitter Compliant IEEE Std 802.16d on FPGA

Abstract

Broadband Wireless Access (BWA) is a promising technology which can offer high speed voice, video and internet connection. The leading candidate for BWA is WiMAX, a technology that complies with the IEEE 802.16 family of standards. This paper is focused towards the hardware Implementation of WirelessMAN-OFDM Physical Layer of IEEE Std 802.16d Transmitter on FPGA. The RTL coding style of Verilog HDL was used which gave a high level design-flow for developing and validating communication system protocols and provides flexibility of modifications in future in order to meet real world performance evaluation. The proposed design is fully supportive to adaptive modulation schemes described in IEEE Std 802.16d and equipped with soft interfaces for MAC layer and RF-front end, so that in future more work could be done in order to deploy complete WiMAX CPE IP core.
