Device for regenerating data from signals transmitted through plural antenna
First Claim
1. A data regeneration device comprising:
- a plurality of despreading units for regenerating pilot and data signals by means of pilot and data Walsh codes;
a path controller for selectively activating the despreading units;
an antenna-waiting signal generator for creating an antenna-waiting signal using the pilot signals output from the despreading units;
an adder for summing 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.

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 OTD, TSTD, STD, or TXAA.
