Abstract
An improved receiver apparatus and acquisition algorithm using TDM pilots is disclosed. The presented timing acquisition method provides the ability to adapt to changing channel conditions, in particular changing expected delay spread. This information about the expected delay spread can be fed back to the original acquisition algorithm based on the delay spread measured at that time, such as setting the length of the detection window used in the previous successful attempt and TDM pilot processing. Based on the delay spread information, an algorithm that handles specialized TDM pilots can adaptively change the timing acquisition parameters for more robust performance under interference conditions. This includes reducing the length of the detection window slightly more than or equal to the maximum expected delay spread, which reduces the sensitivity of fine timing acquisition to signal noise.
