说明：  A software defined radio is a transmitter and receiver system that uses digital signal processing (DSP) for coding, decoding, modulating, and demodulating data. This project focused on using the IEEE 802.11a specification to create a software radio.The feasibility of using Mathwork,s Simulink and Texas Instrument¡ ¯ s Code Composer Studio to design, test, and prototype an OFDM.
