New Channel Estimation Algorithm for Non-Sample-Spaced Channels in Fast Time-Varying OFDM System

New Channel Estimation Algorithm for Non-Sample-Spaced Channels in Fast Time-Varying OFDM System

In fast time-varying OFDM（orthogonal frequency division multiplexing）system, in order to lessen the effects of the CIR（channel impulse response）leakage and ICI（inter-carrier interference）, a new channel estimation algorithm was proposed, which was adapted to non-sample-spaced channels. The algorithm...
