Abstract

In order to improve the efficiency of demodulation processing of a user signal including interference suppression processing, a wireless receiving section (10) which is part of a wireless base station receiving device (1) receives wireless signals (101) containing a plurality of user signal components that are respectively delivered from a plurality of mobile terminals. An interference suppression section (20) determines whether to perform predetermined interference suppression processing during demodulation of each user signal component from the wireless signals (101) (baseband signals (102) that are output from the wireless receiving section (10)), in accordance with the transmission rate (transmission rate information (108)) of each user signal component determined for each mobile terminal, and the reception quality (reception quality information (107)) of each user signal component that needs to be guaranteed for each mobile terminal. In this process, the interference suppression section (20) actuates an interference suppression demodulation block (30) for the number of user signal components identified for the interference suppression processing, and actuates an ordinary demodulation block (40) for the number of user signal components identified as not subject to the interference suppression processing.

Description

technical field [0001] The present invention relates to a radio base station receiving device and a signal demodulation method and a signal demodulation program used therein. Specifically, the present invention relates to a radio base station receiving device and a signal demodulation method and a signal demodulation program used therein for demodulating user signal components respectively corresponding to a plurality of mobile terminals from received radio signals. Background technique [0002] In a mobile communication system, a mobile terminal and a radio base station device communicate with each other through a radio transmission channel. As a communication method that allows a wireless base station device to simultaneously communicate with a plurality of mobile terminals, FDMA (Frequency Division Multiple Access), TDMA (Time Division Multiple Access), CDMA (Code Division Multiple Access), OFDMA (Orthogonal Frequency Division Multiple Access), etc. have been be practica...
