Patent ID: 8259631

Claim:
A method for applying a Time-Varying Cyclic Delay Diversity (TV-CDD) in a wireless communication system, the method comprising: determining whether there is a preamble zone or a data zone of a frame; and when there is the preamble zone of the frame, shifting each of a transmission timing of a partial antenna path signal corresponding to the preamble zone to a first timing and shifting a transmission timing of a remaining antenna path signal corresponding to the preamble zone to a second timing; and when there is the data zone of the frame, maintaining a timing of a reference antenna path signal and shifting each transmission timing of a remaining antenna path signal corresponding to the data zone to a third timing, wherein the first timing is earlier than a reference timing designating an accurate Fast Fourier Transform (FFT) sampling point of a data zone, and the second and the third timings are later than the reference timing.
