Time Delay Estimation for parallel sampling systems

In parallel time-interleaved data acquisition systems, timing mismatch degrades the performance of the whole system. Some initial algorithms for time delay estimation (TDE) were designed under the consideration that only timing mismatch affected at that time. In practical, this is hardly assured. Therefore a new time delay estimation algorithm is proposed in this paper, by the means of signal cross-correlation, which could work efficiently under other channel mismatch or noise is exist.
