Pilot signal transmission method and mobile communication system |
摘要 |
A method of transmitting pilot signals for channel compensation in a mobile communication system based on DFT-spread-OFDM is disclosed. In the disclosed method, a first pilot signal and a second pilot signal are time-division multiplexed together with a data signal of a user into a time-division multiplexed signal which data signal is assigned a certain bandwidth; the time-division multiplexed signal is frequency-division multiplexed together with time-division multiplexed signals of other users when wirelessly transmitted; and the first pilot signal is assigned a bandwidth larger than the bandwidth of the data signal and the second pilot signal is assigned a bandwidth smaller than the bandwidth of the data signal. |
