RECEIVER, TRANSMITTER, AND RADIO COMMUNICATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a receiver, transmitter, and radio communication method capable of utilizing non-orthogonal multiple access while suppressing a cost rise and processing delay.

SOLUTION: A mobile station 200A comprises: a physical channel separation part 210 receiving a radio signal including a plurality of orthogonal signals which are mutually orthogonal and a plurality of non-orthogonal signals which are not mutually orthogonal; and a data demodulation/decoding part 220 which extracts a non-orthogonal signal addressed to the mobile station 200A by demodulating and canceling a radio signal addressed to another mobile station from the plurality of non-orthogonal signals by using an orthogonal signal included in the radio signal received by the physical channel separation part 210, and demodulates a signal addressed to the mobile station 200A included in the orthogonal signal and the extracted non-orthogonal signal addressed to the mobile station 200A.
