Patent ID: 7154935

Claim:
A method for receiving in a mobile station radio signals transmitted from a base station to at least one mobile station, the method comprising: code-despreading the radio signals transmitted from the base station, wherein the radio signals transmitted from the base station have symbols and are code-spread using one code for each mobile station, and are predistorted in accordance with the expected transmission properties regarding each mobile station, and are modulated with regard to their phases; determining the phases of the radio signals for each of the symbols to phase demodulate the radio signals; mapping the determined phases onto a phase zone in accordance with a preestablished rule; forming an average value from a preestablished number of the determined phases; determining a phase correction factor from the average value; and multiplying the phase correction factor by the demodulated radio signals in order to correct a phase error before the radio signals are detected; wherein the phase correction factor is determined using scaling and conjugation of the average value.
