A Study on the OFDM Modem Implementation Using FPGA

This paper describes the design and implementation of the OFDM Modem using FPGA. The proposed OFDM method is based on IEEE 802.11a high-speed wireless LAN standard. The proposed and designed Pipeline FFT processor adopt the Radix-$2^2$SDF scheme. This method has a simple architecture and highly increases the calculation speed. And also it decreases the required number of registers. Therefore the proposed OFDM Modem reduces hardware size and improves the calculation speed. The OFDM Modem is implemented using $FLEX^{TM}$ FPGA.
