Abstract

The invention provides a wireless signal receiving system comprising an antenna used to receive wireless signal, a pre-processor connected with the antenna, a voltage supplying device of the direct voltage used to output different electrical levels, a connector used to provide direct current path and alternating current path, a signal processing module ac coupled with the pre-processor through the connector, a dc-regulator dc coupled with the voltage supplying device through the connector, and a signal detector dc coupled with the voltage supplying device through the connector. The dc regulator is used to receive the direct voltage supplied by the voltage supplying device and provide the first supplying voltage to the pre-processor. The signal detector is used to detect the direct voltage output by the voltage supplying device and generate the control signal to the pre-processor. The pre-processor selectively adjusts the strength of the wireless signal received by the antenna through the control signal to output the data signal and then transport the signal data to the signal processing module through the connector.

Description

Technical field [0001] The present invention relates to a wireless signal receiving system and method, and in particular, to a wireless signal receiving system and method that uses a single transmission line to transmit wireless signals, generate control signals, and provide supply voltages. Background technique [0002] In a general wireless communication system, an antenna for receiving wireless signals and a signal processing module for processing wireless signals are usually included. For example, a wireless electronic device for receiving digital television terrestrial broadcasting (DVB-T) signals needs to be equipped with an antenna and a DVB-T tuner module. [0003] When the position of the wireless electronic device changes, the signal strength received by the antenna also changes. Therefore, the wireless electronic device may be in a certain area (such as an indoor environment), and the signal processing module may not be able to recognize it because the strength of the ...
