Udc 621 . 376 . 3 synthesis of digital radio receiver system for secure communication with frequency-hopping spread spectrum

It was represented the results of synthesis and modeling of work of digital receiver based on the digital down converter (DDC), and a digital signal processor (DSP), which are used to process received signals. The method of constructing narrow-band receiver with digital filtering, demodulation and signal processing, the results of its use in digital radio with frequency-hopping spread spectrum (FHSS mode) is discussed.
