Abstract
Disclosed is an apparatus and method for receiving a channel signal using a STTD (Space Time Transmit Diversity) scheme in a CDMA communication system. In the CDMA communication system a transmitter with first and second antennas STTD (Space Time Transmit Diversity)-encodes a channel signal having PC (Power Control) information of a receiver and transmits a STTD-encoded result over first and second antennas, a first antenna signal processor receives a signal transmitted from the transmitter, and processes the received signal as a signal transmitted from the first antenna using a first pattern, a second antenna signal processor processes the received signal as a signal transmitted from the second antenna using a second pattern orthogonal to the first pattern, and an adder combines an output signal of the first and second antenna signal processor, and generates the PC information, resulting in no delay time while detecting such PC information.
