The task of time selection of the signals from individual radio emission sources (RES) occurs at the station of radio control (RC) whenever at the entrance of the analyzing device combines signals from multiple sources. This problem is solved using a search algorithm [2]. However, this algorithm does not work reliably, if the pulses from the several (usually 3-5) RES present in the mixture. In this case, the probability of forming false estimates of the input sequences. The purpose of this article is to develop an improved algorithm for time selection with a higher accuracy of signal separation in the complex electronic environment. Classification of signals by referring to the wobble of pulses repetition period in the sequence, including the sequence with constant value of the period, dwell and switch, stagger, sliding, wobulaten and jittered sequences are given. Based on the classification improved algorithm for the allocation sequence is developed. The algorithm (Fig. 3) provides analysis of the histogram of the values of the delays between the adjacent pulses of the input mixture. The most probable values of the periods of repetition is allocated on the basis of the analysis of changes in pulses which are related to the signals, composed the mixture. The allocation is from the simple to the more complex signals. After the detection of the individual signal in's pulses are removed from the mixture, and the analysis is repeated. The results of the processing of signal (Fig. 6), including pulse sequences from several sources (Fig. 5) are given.
