ABSTRACT:
An interference reduction receiver is disclosed. The interference reduction receiver includes a weight generating unit for obtaining weights by multiplying a signal correlation matrix of an input signal and a channel response vector. The input signal is despread at two or more predetermined timings, the despread signals are multiplied by the weights, the weight-multiplied signals are added, and an original signal is obtained.
