Abstract
A system and method for DC offset compensation wherein a received first signal is despread using a first spreading code to generate a second signal. The second signal along with a first set of pilot symbols is used to estimate a radio channel. The first signal is also despread using a second spreading code to generate a third signal. A DC offset is estimated from the third signal, the estimated radio channel and a second set of pilot symbols. The estimated DC offset may then be subtracted from the second signal.
