Receiving device and method thereof

摘要

A wireless signal receiving system, having an antenna, for receiving a wireless signal comprising a channel. The system also includes a tuner, coupling to the antenna, for converting the frequency of the wireless signal to generate a conversion signal. In addition, the system includes a processing unit, coupling to the tuner, for controlling the signal receiving direction of the antenna to detect the wireless signals of a first direction and a second direction, using the tuner to generate a first conversion signal and a second conversion signal so as to obtain a first reference value and a second reference value, and generating a control signal according to the first reference value and the second reference value to control the selected receiving direction of the antenna while the antenna is to receive the wireless signal of the channel.

1. A wireless signal receiving system, comprising:
an antenna, for receiving wireless signals comprising a channel; a tuner, coupling to the antenna, for converting the frequency of the wireless signals to generate conversion signals; and a processing unit, coupling to the tuner, for controlling the signal receiving direction of the antenna to detect the wireless signals of only a subset of all directions configured to be received by the antenna, the subset comprising a first direction and a second direction, using the tuner to generate a first conversion signal and a second conversion signal so as to obtain a first reference value and a second reference value, respectively, and generating a control signal according to the first reference value and the second reference value to control the selected receiving direction of the antenna while the antenna is to receive the wireless signal of the channel, wherein the first and second reference values each comprises a signal-to-noise ratio.
