Radio equipment (10) is configured for tap separated channel estimation in a wireless communication system. The radio equipment (10) obtains a channel estimate (16) of a radio channel over which a reference signal (12) is received, and separates the channel estimate (16) into channel estimate components (20) that correspond to respective channel taps (22). The radio equipment (10) then compensates the channel estimate components (20) for Doppler shifts respectively associated with the channel taps (22) to which the channel estimate components (20) correspond. The radio equipment (10) processes the compensated channel estimate components (32) separately. Such processing comprises filtering, interpolating, and/or extrapolating. The radio equipment (10) then de-compensates the processed channel estimate components (34) for the respective Doppler shifts, and forms a combined channel estimate (42) of the radio channel by combining the de-compensated channel estimate components (38).
