Patent ID: 8422608

Claim:
A wireless receiver comprising: a plurality of frequency-space transformers connected to corresponding ones of the receiving antennas, the frequency-space transformers converting signals received for receiving multicarrier transmission waves by the receiving antennas into frequency-space signals; a plurality of noise wave removers connected to corresponding ones of the frequency-space transformers, the noise wave removers each at least performing: calculation of a transmission line coefficient matrix of the multicarrier transmission waves; and calculation of an inter-antenna covariance matrix between the receiving antennas on the frequency-space signals obtained by conversion in the frequency-space transformers; a back-end signal processor for performing a back-end process on signals related to outputs of the noise wave removers; a broadcast interruption detector for detecting a state of interruption of the multicarrier transmission waves; and a back-end controller for controlling the back-end signal processor to operate when the broadcast interruption detector has detected the interruption of the multicarrier transmission waves, wherein the noise wave removers each perform the calculation of the inter-antenna covariance matrix when the broadcast interruption detector has detected the interruption of the multicarrier transmission airwaves.
