METHOD AND SYSTEM FOR FORMATTING CYCLIC PREFIX/POSTFIX IN A MOBILE COMMUNICATION SYSTEM
摘要
<p>A method and transmitter, the method generating a burst containing a first data portion and a second data portion surrounding a training sequence; and appending to the burst a cyclic prefix and a cyclic postfix. Further a receiver on a network element, the receiver configured to: receive a burst containing a cyclic prefix, a cyclic postfix and a data portion; remove at least one of the cyclic prefix or the cyclic postfix; transform the data portion with a discrete Fourier transform; estimate the channel frequency response and modulation of the burst; undo an effect of a channel on the data portion by using the estimated channel frequency response of the channel on the transformed data; use an inverse discrete Fourier transform on the result of the equalizing step; and further process the output of the equalization step to decode the transmitted bits.</p>
