Abstract:
A method for reducing transmission errors by a user equipment (UE) when transmitting a communication signal, comprising the steps of:receiving an RF communication signal at said UE; filtering said received signal to generate a filtered signal using a weighting signal; analyzing said received signal for errors further includes: despreading said filtered signal using a pilot signal; performing a hard decision on said despread filtered signal to generate symbol outputs; and determining a plurality of complex conjugates of said symbol outputs to generate a correction signal; wherein said correction signal removes a plurality of phase errors contained in a plurality of path values; demodulating said received signal to generate said plurality path values for each multipath component in said received signal; generating said correction signal based upon said analysis; mixing said path values with said correction signal to generate said weighting signal; and correcting said communication signal using said correction signal prior to transmission of said communication signal from said UE.
