Abstract:
A mobile communication system having a radio base station apparatus that effectuates communication with radio mobile station apparatuses, wherein:said radio base station apparatus comprises: a signal processing means that receives a multi-wave signal as an input signal, into which spectrum spread codes from a plurality of radio mobile station apparatuses are synthesized, and that performs suppression processing for suppressing interference noise components other than a desired wave in demodulation of a target signal; and a demodulation processing means for performing demodulation processing on spread signals that have been subjected to the suppression processing with respect to the interference noise components; and a number of user signals on which said signal processing means can perform signal processing is smaller than a number of user signals that have been subjected to said suppression processing for suppressing the noise components and that can be demodulated by said demodulation processing means.
