Patent ID: 8224261

Claim:
A transceiver, comprising: at least one antenna element configured to receive an aggregate signal comprising one or more pilot signals; and a processor configured to compute a time delay experienced by at least one of the one or more pilot signals to provide a time delay estimate, and compute a phase rotation experienced by at least one of the one or more pilot signals to provide a phase estimate, wherein the time delay for at least one of the one or more pilot signals is computed by the following formula: τ i =arg max C i (τ), wherein τ i , is the time delay estimate for an i th pilot signal, and C i (τ) is defined as C i (τ)=|∫r(t)s i *(t−τ)dt| 2 , for 0<τ<T., wherein r(t) is the aggregate signal, s i *(t−τ) is a conjugate of the i th pilot signal delayed by τ, and τ is a delay hypothesis.
