DIVERSITY SYSTEM FOR IMPROVING THE RECEIVING SENSITIVITY OF BROADCASTING SIGNAL AND METHOD FOR CONTROLLING THE RECEIVING SENSITIVITY OF ITS SYSTEM

摘要

The present invention relates to a diversity system and a control method thereof, a plurality of antennas consisting of two or more to receive a broadcast signal to improve the reception sensitivity of the broadcast signal; An antenna switching unit for selecting any one of said plurality of antennas; RF tuning unit for tuning to the broadcast frequency of a broadcast signal received from the selected antenna from the antenna switch portion; A / D converter for converting the IF signal from the analog to digital signal from the RF tuning unit; The A / D decoder for demodulating the digital signal output from the conversion unit, to restore the correct, error of the compressed signal and the detected bit rate; Amplifying such a signal processor for amplifying the output signal from said decoder unit; And receiving a bit-rate from the decoder unit includes a microcomputer for controlling the antenna switching unit to select one of the plurality of antennas. Therefore, it is possible to move the vehicle to receive signals of the receiving sensitivity is enhanced digital TV / radio while driving.
