The present invention provides a method for transmitting pilots in a multi-carrier wireless transmission system. A wireless time-frequency transmission block is composed of N consecutive OFDM symbols in time domain and M consecutive physical sub-carriers in frequency domain, N and M are integers those are greater than or equal to 1. The method includes: partitioning the wireless time-frequency transmission block into several areas, and determining the position of pilots, of which the total number is a preset number, according to the time-frequency domain balancing principle of pilots of various antennas in various areas; inserting pilots at the pilot positions of each antenna corresponding to the antenna for transmission. In accordance with the present invention, the simultaneous transmission of multiple antennas is supported in a wireless time-frequency transmission block of a multi-carrier wireless transmission system. |
