A radio receiving system has a plurality of interference cancelers. Received signals are separated and demodulated by an adaptive array (AA), a parameter estimating section (PE), and a detector (DE) of each of the interference cancelers into the signals of the respective users and outputted from a processing circuit (200) lastly. A demodulated signal demodulated without any demodulation error is removed from the received signals, the interference due to the user signal is removed, and the resultant received signals are sent to the next interference canceler. Users are assigned to the same time slot in such a way that the difference between the reception powers of the user signals are as large as possible. Thus at least one of the user signals is demodulated without any error by each interference canceler and removed from the received signals. Therefore, the signal of each user can be extracted reliably by this radio receiving system of the PDMA method.
