RU94001388A - Generator of n-digit random sequence - Google Patents

Abstract

FIELD: computer engineering, radio engineering for complex signal processing. SUBSTANCE: initially control unit outputs pulses with rates of F, F, F, ..., Fto first, second and so on till n-th shift input of respective shift registers which generates reference sequences of random numbers with periods iT, (i+2)T, ..., nT; while time for generation of each sequence is equal for all of them. Then, each bit from outputs of shift registers is sent to intermediate memory unit which output lines provide n-digit random sequence according counting pulse from control unit. EFFECT: simplified design.

The invention relates to computing, and in particular to devices simulating random processes, and can be used in radio systems with complex signals. The aim of the invention is to simplify the generator of an n-digit pseudo-random sequence. This goal is achieved by the fact that at the initial moment of time from the outputs of the control unit pulses with repetition frequencies F, F ² , F ⁴ , ..., F ^{2 (n-1)} arrive at the first, second, etc. n-th the shift input of the corresponding shift registers, which form the reference sequences of the PSC with periods iТ, (i + 2) Т, ..., nТ, but with the same generation time of the latter. Next, each bit from the outputs of the shift registers is transferred to the intermediate memory, from the output buses of which, by the command of the count pulse coming from the control unit, an n-digit SRP will be removed.
