Formulation of the problem. The article considers the issues of choosing low-pass filters with finite and infinite pulse characteristics used to generate CBOC signals with phase manipulation with a reduced level of out-of-band radiation.

Purpose. The influence of the filter frequency band on the distortion of CBOC signals in the frequency and time domain is estimated by mathematical modeling.

Results. The following filter parameters, peak factor and ACPR (Adjacent Channel Power Ratio) were studied and calculated.

Practical significance. The results obtained can be used by developers of local navigation systems.
