摘要: An OFDM receiver receives symbols in the frequency domain and comb filters then punctures to leave with actual pilot information null values at data symbols. The provides punctured an symbol queue. A virtual interpolator is coupled storage generate introduced may be a two dimensional Wiener filter. also includes time channel estimator that processes first including impulse response for symbol. equalizer equalizes
