Abstract

In a wireless receiving device, an AGC control unit (16) adjusts a variable gain of a receiving amplifier (2) for each frame of a received signal, and executes an AGC operation. The AGC control unit (16) determines the AGC operation end time and notifies the digital signal processing unit (15). A digital signal processing unit (15) performs predetermined signal processing on a digital signal obtained after the AGC operation is completed within a known signal interval. This prevents reception errors from occurring due to incorrect amplitude values ​​of digital signals based on AGC operations.

Description

technical field

[0001] The present invention relates to a wireless receiving device, a signal processing timing control method, and a signal processing timing control program, and in particular to a wireless receiving device, a signal processing timing control method used in a mobile communication system such as a base station that requires high communication quality such as data communication. A control method and a timing control program for signal processing. Background technique

[0002] Conventionally, automatic gain control (Automatic Gain Control: AGC) has been widely used in wireless receiving apparatuses in order to converge the level of a received signal to a desired level. Figure 5 It is a schematic block diagram showing the configuration of a wireless receiving device used in a mobile communication system (base station or mobile station thereof) such as PHS (Personal Handyphone System) as an example of a conventional wireless receiving device using AGC.
