WIRELESS BASE STATION RECEIVING DEVICE, AND SIGNAL DEMODULATION METHOD AND PROGRAM USED THEREIN
First Claim
1. A wireless base station receiving device comprising:
- a reception unit that receives a wireless signal including a plurality of user signal components respectively transmitted from a plurality of mobile terminals; and
a determination unit that determines whether to perform a predetermined interference suppression processing upon demodulation of each user signal component from the wireless signal, according to a reception quality of each user signal component that needs to be guaranteed for each mobile terminal, and a transmission rate of each user signal component determined for each mobile terminal.

Abstract
In order to improve the efficiency of user signal demodulation processing including interference suppression processing, a wireless receiving unit (10) forming a wireless base station receiving device (1) receives a wireless signal (101) including plural user signal components respectively transmitted from plural mobile terminals. An interference suppression unit (20) determines whether to perform a predetermined interference suppression processing upon demodulation of each user signal component from the wireless signal (101) (base band signal (102) output from the wireless receiving unit (10)) according to a reception quality (reception quality information (107)) of each user signal component that needs to be guaranteed for each mobile terminal and a transmission rate (transmission rate information (108)) of each user signal component determined for each mobile terminal. At this time, the interference suppression unit (20) causes a number of interference suppression demodulation blocks (30) corresponding to the number of user signal components determined to be subjected to the interference suppression processing to operate, and causes a number of normal demodulation blocks (40) corresponding to the number of user signal components determined not to be subjected to the interference suppression processing to operate.
