Patent ID: 7953141

Claim:
An interference reduction receiver, comprising: a signal correlation matrix obtaining unit configured to obtain a signal correlation matrix separate from despreading based on an input signal; a weight generating unit configured to generate weights by multiplying the signal correlation matrix of the input signal by a channel response vector; and a demodulating unit configured to demodulate a signal by despreading the input signal at a plurality of predetermined timings to obtain despread signals, multiplying the despread signals by the weights to obtain weight-multiplied signals, and adding the weight-multiplied signals; a delay unit configured to provide a time delay to the input signal, the time delay being equal to a difference between a first path timing and a second path timing; a multiplication unit configured to multiply the input signal and an output signal of the delay unit; an averaging unit configured to average an output signal of the multiplication unit to obtain components of the signal correlation matrix corresponding to the first path timing and the second path timing.
