摘要：
A method for deriving a channel transfer function from an Orthogonal Frequency-Division Multiplex (OFDM) signal received over a channel and having unmodulated sub-carriers and sub-carriers modulated with symbols, includes the steps of sampling the received OFDM signal at a sampling rate greater than the bandwidth of the OFDM signal, deriving from the sampled OFDM signal a set of time domain coefficients representative of the channel impulse response, and deriving from a subset of the set of time domain coefficients a channel transfer function in the frequency domain.
