Abstract
A transmission/reception apparatus and method are provided for channel estimation in a mobile communication system for transmitting packet data based on FDMA, and include a transmitter for transmitting signals through a pilot channel and a control channel, and a receiver for receiving the signals of the pilot channel and the control channel and estimating a channel for demodulation of a data channel using the signal of the pilot channel and information about transmission power used when the control channel is transmitted. The receiver includes a pilot channel receiver, a control channel receiver, a control channel signal reproducer, and a channel estimator for performing channel estimation using the signals received through the pilot channel, the control channel, the signal transmitted through the control channel by the transmitter, and the information about transmission power used when the control channel is transmitted by the transmitter.
