A system and method for estimating Doppler shift compensation in a mobile communication
system is described. A channel impulse response determination circuit determines
a channel impulse response for the channel on which the signal is received. A reference
vector is generated using a set of known symbols and the channel impulse response,
and an error vector is then generated by comparing the reference vector with received
samples of the signal. In addition, the noise variance of the incoming signal can
be determined. Then, a Doppler correction factor is estimated having a real part
representing amplitude correction and an imaginary part representing phase correction.
