Abstract:
1. A smart antenna control system, comprising: a smart antenna system for forming an antenna pattern suitable for signal reception by receiving mechanical or electrical antenna control signal and controlling a beam width, gain, and frequency characteristic; a VSB demodulator for generating channel data for demodulating a VSB (Vestigial Side Band) signal received through the smart antenna system, generating channel data for the antenna pattern, and outputting the demodulated VSB signal in a transport packet form; and an antenna controller for receiving the channel data and auto gain control information from the VSB demodulator and controlling the smart antenna system by using the auto gain control information and the channel information, wherein the antenna controller is adapted to acquire a maximum signal power by calculating signal power using a fixed specific value of the auto gain control information and detecting the maximum signal power.
