ABSTRACT:
A method and apparatus are provided that corrects for differences in reception between a user-specific signal and a common signal. In one embodiment, the invention includes receiving a common pilot signal transmitted on a wide beam at a remote terminal, receiving a user-specific signal transmitted on a directed narrow beam at the remote terminal, demodulating the user-specific signal using the common pilot signal for channel estimation, estimating a phase error in the demodulated user-specific signal using known symbols in the user-specific signal, and correcting for the phase error in the demodulated user-specific signal using the phase error estimates.
