Abstract

A receiving device for a mobile station receives signals transmitted from a base station having a time-switched transmission diversity (TSTD) function. In the receiving device, a despreader despreads channel signals which have been transmitted in a TSTD mode of operation. A pilot separator separates a pilot signal from the despread channel signals. A channel estimator generates a channel estimation signal by selecting pilot signals transmitted from a same antenna of a transmitter according to a TSDT pattern of the transmitter. A compensator compensates the channel signals with the channel estimation signal.
