RSSI PRESENTING APPARATUS IN WIRELESS RECEIVER, RSSI PRESENTING METHOD IN WIRELESS RECEIVER, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an RSSI presenting apparatus for presenting an RSSI without using an IC for directly finding the RSSI from a receiving signal in a wireless receiver. SOLUTION: A feedback part 100 calculates output signal strength information I2+Q2from level information of an I signal and level information of a Q signal, adjusts control level information CL so that the output signal strength information I2+Q2can be close to an expected target value, and performs AGC control on a variable gain amplifier 40. A storage part 4 stores, in advance, corresponding relation information indicating a corresponding relation of a receiving signal strength RSSI and the control level information CL. A conversion part 3 searches an RSSI value corresponding to the value of the control level information CL that is imparted from the feedback part 100 and acquired by a control level information acquisition part 2, from the storage part 4 and presents the searched value as the RSSI to a control part 70.
