Abstract
Disclosed is a transmission/reception apparatus and method for providing compatibility between Code Division Multiple Access (CDMA) and Orthogonal Frequency Division Multiplexing (OFDM) in a forward link. The proposed transmission/reception apparatus and method uses a traffic channel based on OFDM while using a pilot channel and a sync channel used in the CDMA scheme. Thus, a transmitter adds a pilot channel signal and a sync channel signal to OFDM-modulated symbols before transmission, and a receiver acquires a pilot channel signal and a sync channel signal, and removes them from a received signal, thereby outputting only pure OFDM-modulated symbols.
