Abstract
A user device receives, from a base station, a radio signal in which non-orthogonal signals are mixed. The user device recognizes, based on information transmitted from the base station, a parameter associated with the location of the user device. When the user device is at the edge of the cell area of the base station, a demodulator of the user device demodulates, as a signal directed to the user device, the radio signal in which an interference signal component has been suppressed by an interference rejection combining processor of the user device and a non-orthogonal signal canceller of the user device does not operate. When the user device is within the cell area and is not at the edge of the cell area, until the demodulator demodulates the signal directed to the user device, the interference rejection combining processor suppresses an interference signal component in a non-orthogonal signal outputted from the non-orthogonal signal canceller and the demodulator demodulates the non-orthogonal signal in which the interference signal component has been suppressed by the interference rejection combining processor.
