Hardware Implementation of an OFDM Transceiver for 802.11n systems

The best approach for real time application to achieve high throughput and network capacity for fourth generation wireless local area networks is to combine MIMO wireless technology with OFDM. This paper focuses on high level Matlab Simulink 4 x 4 spatially multiplexed (SM) MIMO OFDM transceiver encoded at 1⁄2 rate using 64 size FFT which is designed and implemented on Spartan Virtex 6 FPGA board. The hardware co-simulation, RTL Schematics, Test Bench and VHDL codes for all the blocks and for the complete 4 X 4 MIMO OFDM model are obtained to verify its functionality.
