摘要: In an orthogonal frequency division multiplexing (OFDM) system, a domain channel estimate for non-nullified subcarriers is converted to time estimate. The number of taps L model determined based on the An improved obtained by computing tap coefficients from performing Fourier transform Alternatively, truncation method may be performed selectively only if signal-to-noise ratio (SNR) below threshold. pilot are and delay spread.
