Annotation: This article examines one of the options for implementing a communication system with pseudo-random digital modulation. For such systems the spreading factor (the signal base) is an important parameter. This work contains the results of operability study for the system in multi-user radio channel. During numerical simulation it was established how the correlator length depends on the number of users simultaneously working in the common frequency band. It is shown that this dependence has a quadratic character.
