Implementation of MB-OFDM Transmitter Baseband Using FPGA Approach for High Speed Application
An enhancement to the FDM system, as MB-OFDM, has been proposed to reduce the complexity and power consumption without sacrificing performance. In this paper, the authors presented the detailed FPGA implementation of a complete-OFDM transmitter. The entire transmitter can be mapped onto a single FPGA chip. 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 Vertex FPGA.
