A Simple Way to Deinterleave Repetitive Pulse Sequences

This paper presents a simple but efficient algorithm for deinterleaving of periodical pulse sequences. Based upon time of arrival analysis, one or more pulse repetition intervals are determined from the sequential difference histogram just by detecting the maximum value in the histogram. The algorithm is compared to some typical signal sorting methods and implemented in C language program. It is shown that, the proposed algorithm is timesaving, efficient and easy to implement for real-time applications comparing with those based upon threshold functions or transform computing which is time-consuming.
