Reception device and reception method

摘要

A reception device (100) includes: AGC circuits (103) to generate electric power information individually indicating signal strengths of respective received signals generated from a respective plurality of radio waves received at a plurality of places; stationary-state detection circuits (105) to calculate individually the amounts of time domain fluctuation in the respective signal strengths indicated by the electric power information generated by the AGC circuits (103), and to detect individually, on the basis of the respective calculated amounts of fluctuation, whether the reception device (100) is stationary or not; and a self-stationary determination circuit (106) to determine, on the basis of a plurality of detection results from the stationary-state detection circuits (105), whether the reception device (100) is stationary or not.

1. A reception device for receiving radio waves, comprising:
an automatic gain control unit to generate electric power information individually indicating signal strengths of respective received signals generated from each of radio waves received at a plurality of antennas installed at a plurality of different places on a vehicle; a stationary-state detection unit to calculate individually amounts of time domain fluctuation in the respective signal strengths indicated by the electric power information generated by the automatic gain control unit, and to detect individually, on the basis of the calculated amounts of fluctuation, whether the reception device is stationary or not; and a self-stationary determination unit to determine, on the basis of a plurality of detection results from the stationary-state detection unit, whether the reception device is stationary or not.
