Abstract:
Providing for improved tracking and correction of timing in wireless communications is disclosed herein. By way of example, a first algorithm can be employed to track timing of a wireless signal, based on one dimension of the signal. Additionally, a second algorithm based on a different dimension of the signal can be employed to verify the timing and reduce errors in timing analysis. Various signal dimensions can be employed for the analysis, including cyclic prefix, frequency, channel impulse response, or the like, or a combination thereof. Additionally, different channels of the wireless signal can also be analyzed by the first algorithm and the second algorithm. Furthermore, the second algorithm can be selected to reduce deficiencies identified in the first algorithm, to improve overall timing analysis, reduce undetected timing errors or false errors, and improve timing correction.
