摘要: In orthogonal frequency division multiplexing (OFDM) systems, multipath fading channels introduce interference between adjacent symbols. Although the degrades system performance considerably, it also provides information of channel impulse response (CIR) length to us. Therefore, based on estimation in cyclic prefix (CP) interval, we can use minimum description (MDL) criterion detect blindly.
