Patent ID: 8300651

Claim:
A method for a user equipment device, the method comprising: receiving a reference signal from a desired transmitter; obtaining information about at least one interfering transmitter whose signals are receivable by said user equipment device, said information including a reference signal sequence of a reference signal transmitted by said at least one interfering transmitter; calculating filtering characteristics of a signal filter based on the information obtained about the at least one interfering transmitter, said calculating comprising: estimating a power of signals transmitted by said desired and said interfering transmitter, a noise variance, and time and frequency correlation matrices; generating a channel correlation matrix from said time and frequency correlation matrices; constructing an autocorrelation matrix of the received reference signal and a cross-correlation matrix of said received signal with said channel from said estimated power, said noise variance and said reference signal sequence for said interfering transmitter; and generating said signal filter from said autocorrelation matrix and said cross-correlation matrix; applying said signal filter using said calculated filtering characteristics to filter said received reference signal; and generating a channel estimate for a channel between said user equipment device and said desired transmitter using said received reference signal and said information.
