    摘要： An improved receiver apparatus and acquisition algorithm using TDM pilots is disclosed. The timing acquisition method presented provides capabilities for adapting to changing channel conditions, in particular varying expected delay spreads. The information on an expected delay spread can be fed back to the initial acquisition algorithm based on previous successful attempts, and the delay spreads measured at that time, such as to set the length of the detection window used to in the TDM pilot processing. Based on the delay spread information, the algorithm for processing the specialized TDM pilot can adaptively modify the timing acquisition parameters for more robust performance under interference conditions. This may involve reducing the length of the detection window to just a little more than or equal to the maximum expected delay spread, which reduces sensitivity of the fine timing acquisition to signal noise.
