Abstract: The channel estimation technique employs a set of pilot tones to determine channel state information. Because some of the pilot tones contained in the OFDM symbols may be missing after transmission, the disclosed technique employs a set of known pilot tones to compute an estimate of the channel impulse response, which may exhibit a level of distortion. Non-zero terms of the estimated channel impulse response that fall outside of a prescribed time window are regarded as artifacts of a set of missing or unknown pilot tones. Information relating to the known pilot tones and the artifacts of the unknown pilot tones are employed for mathematically reconstructing and deriving values of the unknown tones. Then, the values of the known pilot tones and the derived values of the unknown pilot tones are employed to recompute the channel impulse response, thereby obtaining the channel estimate with a reduced level of distortion.
