Abstract: This paper presents a new clock-control model which is a combined model of cumulative function and the clock-control generator. This new edited sequence’s data rate, period, linear complexity, 1-complexity of weight are discussed. It is shown that the editing sequence has pseudo-randomness of high data rate, large period, large linear complexity and so on. This model can be simple put into practice and promotion. So it is a good pseudo-random sequence suitable for practical implementation of signal code systems.

Key words: cumulative function, Linear Feedback Shift Register(LFSR), linear complexity, 1-complexity of weight, stream cipher
