A CORRECTION METHOD OF TIME-VARYING CHANNEL ESTIMATION IN A TIME-SLOTTED MOBILE COMMUNICATION SYSTEM |
摘要 |
A correction method for time varying channels in a time slot division mobile communication system that includes: performing channel estimation and signal detection for a time-slot or burst signal received with a time invariant block processing method; estimating the channel deviation by using the detection result of some symbols that are near the channel estimation code; correcting the channel estimation with the estimated channel deviation; and demodulating the said detection result with the corrected channel estimation. The procedure can be carried out once or for a plurality of times. This correction method is adaptive to a certain degree of varying of the channel response within a time-slot while keeping the basic characteristics of the block processing method, softening the terms of application thereof in a time-slot CDMA system or similar block processing systems and improving the performance of system under the circumstances of larger frequency deviation and shift as well as higher moving speed of a terminal. |
