| Abstract: | OFDM (Orthogonal Frequency Division Multiplexing) is a popular topic of research and application in high speed wireless communication field, it is generally regarded as one of the core technologies in the 4th mobile communication system due to its good performance against multi-path fading, high frequency efficiency and self-adaptation modulation. This paper studies the OFDM technology based on 802.16a, realizes the baseband modulation and demodulation by using TMS320C6201, and optimizes the software module, with the bit rate up to 1.32Mbit/s. |
