Claim:
1. A receiver comprising: circuitry configured to receive radio signals including a plurality of non-orthogonal signals which are not orthogonal to each other; extract a non-orthogonal signal addressed to the receiver from the plurality of non-orthogonal signals received by the circuitry, by demodulating and cancelling a radio signal addressed to another receiver; and demodulate the extracted non-orthogonal signal addressed to the receiver, wherein a radio resource block allocated to the non-orthogonal signals is defined in a frequency domain, a time domain and a non-orthogonal multiplex domain, the non-orthogonal multiplex domain has a plurality of levels corresponding to a number of interference cancellations by the circuitry, the circuitry cancels the non-orthogonal signal whose allocated radio resource block is at a lower level than that of the receiver, wherein the number of interference cancellations is determined from a number of path losses associated with the received radio signals, and wherein a radio resource block at a higher level associated with interference cancellations is allocated for a smaller path loss than a radio resource block at a lower level associated with interference cancellations that is lower than the higher level.
