| 成果简介 | NOVELTY - The device for determining noise immunity has a receiving antenna (1) whose output is connected to the first input of a dual-frequency receiver (2). The output of dual-frequency receiver is connected to the first input of an analog-to-digital primary processing processor (4). The output of the primary reference generator and frequency synthesizer (3) is connected to the signal phase path calculation unit (5). The output of the signal phase path calculation unit is connected to the first input of the total electron content of the ionosphere calculation unit (6). A parameter determination unit (11) determines the parameters of a decameter radio path. A signal/noise ratio determination unit (16) determines the signal/noise ratio at the reception point. The output of signal/noise ratio determination unit is connected to the third input of the error probability determination unit (15) for determining the probability of error. USE - Device for determining noise immunity of digital signal reception in decameter communication channel under conditions of ionospheric diffusion used in modern digital decameter (DCM) radio communication systems. ADVANTAGE - The device for determining the noise immunity of digital signals in the DCM communication channel under ionospheric diffuseness conditions does not contain a threshold device unit and a data processing unit. The determination of the noise immunity of the DCM communication channel when using digital types of modulation is carried out at any values of the intensity of small-scale inhomogeneities of the ionosphere electron concentration. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a device for determining the noise immunity of digital signal reception in a DCM communication channel under conditions of ionospheric diffusion. 1Receiving antenna 2Dual-frequency receiver 3Primary reference generator and frequency synthesizer 4Analog-to-digital primary processing processor 5Signal phase path calculation unit 6Ionosphere calculation unit 11Parameter determination unit 15Error probability determination unit 16Signal or noise ratio determination unit |
