Implementation of MB-OFDM Transmitter Baseband Based on FPGA

Abstract

Multi-Band Orthogonal Frequency Division Multiplexing (MB-OFDM) is a suitable solution to implementation of high speed data transmission in ultra wideband spectrum by dividing the spectrum available into multiple bands. The baseband of transmitter is one of the most important parts in MB-OFDM system. The structure of MB-OFDM system transmitter is introduced in this paper and the design of transmitter baseband based on FPGA is described in detail. The design has been validated with Xilinx Virtex II FPGA. The results show that all modules designed has achieved the expected purpose both in precision and resource, with simplicity and high efficiency, and can meet the demand of MB-OFDM systems.
