Abstract

A pilot symbol structure and a pilot transmission method for improving channel estimation performance in a wireless access system using multiple carriers are provided. In the method for transmitting subcarriers using a pilot structure, pilot subcarriers are repeatedly allocated at predetermined subcarrier spacings and at predetermined symbol spacings in a basic resource block, and the basic resource block is periodically and repeatedly allocated in a time domain and a frequency domain within a subframe, and then the pilot subcarriers and data subcarriers included in the subframe are transmitted. When one or more antennas are used, it is possible to transmit pilot symbols while maintaining predetermined spacings in the time domain and the frequency domain, thereby improving channel estimation performance.
