Using known signal ensembles built on the basis of linear and nonlinear recurrent sequences, it is difficult to obtain signal ensembles with large volumes and satisfactory intercorrelation characteristics. The purpose of the article is the development of a method for the synthesis of complex signals ensembles of large volume by dividing the spectrum of the descending pseudo-random sequences with low interaction in the time domain into bands with subsequent transmission of the received signals in another range and subsequent permutations. The article presents the results of the development of the formation method of complex signals ensembles of increased volume based on the use of frequency bands using the process of transferring frequency elements in the operating frequency domain of LTE technology and subsequent permutations. Applying multiple filtering to descending pseudo-random sequences with low interaction in the time domain with re-filtering of the received signals and their subsequent permutation allows increasing the maximum volume of the signal ensemble compared to existing complex signal ensembles used in modern radio communication systems with code division multiplexing
