摘要： Embodiments of the invention provide method and apparatus for generating a structure in an orthogonal frequency division multiplexing OFDM communication system having a transmitter with one or more transmitting antennas. The method includes composing a frame with a time domain and a frequency domain. The frame has a transmission time interval in the time domain and occupies a bandwidth in the frequency domain. The transmission time interval has multiple orthogonal frequency division multiplexing symbols. A pilot signal is located from a transmitting antenna into two non-consecutive orthogonal frequency division multiplexing symbols of the frame.
