Radio signal receiving control device and the control method for the same

摘要

A radio signal receiving control device and the control method for the same. The disclosed radio signal receiving control method is to utilize the phenomenon that when IF frequency between the radio transmitter and the receiver shifts the bit duration received will change accordingly, to detect the bit duration variation of received data, thus adjusting the frequency of local oscillator signal. In the radio signal receiving control device, an AND gate connects to the output terminal of the radio signal receiving device and a counter connects to the AND gate. A feedback controller connects to the counter and a comparer, a digital/analog converter connects to the feedback controller. A varactor diode connects to the digital/analog converter and a local oscillator of the radio signal receiving device
