| Popis: | 95 My study is focus on low complexity ICI cancellation on OFDM in very high mobility environment. In conventional OFDM system, because of time-varying fading channels, subcarrier energy leak to other subcarriers. It destroys the orthogonal relation among all subcarriers in OFDM system, Conventional ICI cancellation method is difficult to be realized for its high complexity, so we proposed a low complexity ICI cancellation method. We lowered its complexity from the receiver and transmitter, and added the existed information of railroad system to improve performance of OFDM system. |
