ABSTRACT:
A device for restoring data from signals transmitted through plural antenna includes a plurality of despreading units to restore pilot and data signals by means of pilot and data Walsh codes, a path controller to selectively activate the despreading units, an antenna-waiting signal generator to generate an antenna-waiting signal with the pilot signals output from the despreading units, an adder to sum the data signals output from the despreading units, and a controller to control the path controller and the adder in accordance with a transmission scheme of a base station. The invention provides one receiver system for a mobile terminal to be adaptable to various environments of transmission diversity with base stations, such as orthogonal transmission diversity (OTD), time-switched transmission diversity (TSTD), selection diversity (STD), or transmission antenna array (TXAA).
