Abstract
A receiving apparatus is provided in which a single carrier signal is received by a plurality of receiving antennas, and multipath equalization and other cell interference suppression are carried out in a frequency domain at a same time. A plurality of antennas-to-N receives the single carrier signal. The DFT sections-to-N converts the reception signals into frequency domain signals. A channel estimating sectionestimates a channel gain of a desired user signal by using pilot reception signals. An interference correlation matrix estimating sectionestimates an interference correlation matrix from the pilot reception signals and a channel estimation value. A weight calculating section. A weight calculating sectionreceives the channel estimates and the interference correlation matrix and calculates equalization weights. An equalizing sectionperforms multipath equalization and other cell interference suppression to the desired user signal in a frequency domain. An IDFT sectionconverts an equalization signal into a signal in a time domain.
