Low utilization FPGA implementation of OFDM transceiver based on IEEE 802.11n standard

Orthogonal Frequency Division Multiplexing (OFDM) is considered as one of the most important techniques in the wireless communication field, it's used by many standards such as Wi-Fi standards 802,11a/n/ac. The basic principle of OFDM is transmitting data by dividing the stream into several parallel bit streams and modulating each of these data streams onto individual orthogonal carriers or subcarriers. This paper includes the design and the implementation of an OFDM transceiver based on 802.11n standard. All the modules are designed using Verilog hardware description language. The transceiver is implemented on FPGA, then tested and compared with a MATLAB reference model, achieving lower utilization than most of the pervious related work presented before.
