RECEIVER, TRANSMITTER AND RADIO COMMUNICATION METHOD

摘要

A mobile station includes: a physical channel segmentation unit to receive radio signals including multiple orthogonal signals which are orthogonal to each other, and multiple non-orthogonal signals which are not orthogonal to each other; and data demodulating/decoding units to extract the non-orthogonal signal addressed to the mobile station from the multiple non-orthogonal signals by demodulating and cancelling the radio signal addressed to another mobile station by use of the orthogonal signals included in the radio signals received by the physical channel segmentation unit, and demodulate the signal included in the orthogonal signals and addressed to the mobile station, and the extracted non-orthogonal signal addressed to the mobile station.

1. A receiver comprising:
a radio signal reception unit configured to receive radio signals including a plurality of orthogonal signals which are orthogonal to each other, and a plurality of non-orthogonal signals which are not orthogonal to each other; an interference cancelation unit configured to extract the non-orthogonal signal addressed to the receiver from the plurality of non-orthogonal signals, by demodulating and cancelling the radio signal addressed to another receiver by use of the orthogonal signals included in the radio signals received by the radio signal reception unit; and a demodulation unit configured to demodulate the signal included in the orthogonal signals and addressed to the receiver, and the non-orthogonal signal extracted by the interference cancelation unit and addressed to the receiver.
