METHOD AND A DEVICE FOR RECEIVING A DIGITAL TV SIGNAL BY USING A SPACE DIVERSITY AND BEAM FORMING FUNCTION, PARTICULARLY CONCERNED WITH REALIZING A FAST CONVERGENT SPEED, AND REDUCING A BURDEN ON CHANNEL COMPENSATION

摘要

PURPOSE: A method and a device for receiving a digital TV signal by using a space diversity and beam forming function are provided to improve the quality of a received digital TV signal by using a space diversity and at least one beam former, thereby realizing a fast convergent speed while reducing a burden on channel compensation. CONSTITUTION: Plural converters(12-1¯12-M) convert received radio signals into baseband signals, respectively. A channel estimator(13) receives output signals of the plural converters(12-1¯12-M) and output signals of plural beam forming units(14-1¯14-N), estimates a channel for a corresponding antenna element, and outputs control signals. Controllers(22-1¯22-N) receive the output signals of the beam forming units(14-1¯14-N), and delay the received signals to output the delayed signals. An adder(26) combines output signals of the controllers(22-1¯22-N).
