Abstract:
1. A method for transmitting traffic data in a transmission apparatus for generating a pilot signal, spreading the pilot signal using a first channelization code, and generating a pilot channel signal having a predetermined chip rate by scrambling the spread pilot signal using a pseudo-random noise (PN) sequence in a mobile communication system, the method comprising the steps of: generating an Orthogonal Frequency Division Multiplexing (OFDM) signal by modulating the traffic data having the same sample rate as the predetermined chip rate; summing the OFDM signal and the pilot channel signal, and transmitting the summed signal; and spreading the sync signal using a second channelization code, generating a sync channel signal having the predetermined chip rate by scrambling the spread sync signal using the PN sequence, and summing the sync channel signal, the OFDM signal and the pilot channel signal.
