Abstract:
1. An apparatus for receiving power control (PC) information in a communication system wherein a transmitter with first and second antennas space time transmit diversity (STTD)-encodes a channel having the PC information of a receiver and transmits a STTD-encoded result over the first and second antennas, comprising: a first antenna signal processor adapted to receive a signal transmitted from the transmitter, and multiply the received signal as a signal transmitted from the first antenna with a first pattern; a second antenna signal processor adapted to multiply the received signal as a signal transmitted from the second antenna with a second pattern orthogonal to the first pattern; and an adder adapted to combine an output signal of the first antenna signal processor with an output signal of the second antenna signal processor, and generate the PC information.
