Implementation of OFDM Baseband of IEEE802.11a Based on FPGA

In this paper,according to the 802.11 wireless LAN baseband OFDM modulation,the specific FPGA implementations are given.And a buffer-based flow control mechanism is used for data burst mode and continuous mode.And for the insertion in the pilot,as well as arrangements for the realization of the spectrum,FIFO plus RAM approach is used.As for the PLCP training sequence,a look-up table based on ROM is designed.BPSK and 16QAM modulation modes are used.A smaller delay would rather welcome than a less consumption of resource of hardware in this design.The spectrum structure and time-domain frame structures meet the design requirements through the verification,and perform better in the property of time delay.
