摘要: A method and apparatus in a multiple sub-carrier digital communication receiver that estimates channel. second set of channel are generated based on Wiener filter interpolation first estimates. Pre-determined transmit pilot symbols may be used to generate the an OFDM system. The coefficients impulse response estimate includes two or more narrow regions non-zero amplitude separated by one wide essentially zero amplitude. also Doppler frequency estimate. determined from estimates, while pre-determined responses.
