Abstract :
SD-OFDM has been proposed for information transmission with high spectrum efficiency. In this paper, an adaptive SD-OFDM (ASD-OFDM) is proposed for time- frequency selective fading channel. Compared with traditional OFDM, the ASD-OFDM improves the performance, i. e., spectrum efficiency and interference cancelation capability, in the high speed mobile scenario as well as short-delay multipath environment.
