In this) the same modulation method can be used, for example, the transition from wide-band to narrow-band frequency modular module, or another type of modulation, more suitable for data transmission, modulation, parapherical transition from wide-band frequency mode: 1 chip to phase or frequency mapipulations with temporal separation of signals.
