Description

The invention relates to radio engineering and can be used to form composite, complex noise-like signals in radio transmitting devices of information transmission systems and communication with increased structural secrecy.

The purpose of the invention is to enhance the functionality by performing frequency and / or phase shift keying.

The drawing shows an electrical block diagram of a device for generating complex signals.

The device for generating complex signals contains a clock generator 1, a sinusoidal shaper 2, a frequency divider 3, a code sequence shaper 4, a switch 5, first and second processing channels 6 and 7, a shaper 8 control pulses, a shaper 9 pulses, and a HE element 10

The first and second processing channels 6 and 7 are identical and each of them contains a decoder 11, a generator tel 12 pulses, a counter 13, an element OR 14, and a fixed memory unit 15. The control pulse driver 8 comprises a pulse shaping unit 16, a HE element 17, the first and second elements AND 18, and a clock generator 20,

A device for generating complex signals operates as follows.

The mode of forming the type of signal is set by the operator depending on the effect on the control inputs of the buses F and tires (jt To form a FM signal, the operator acts on the control inputs of the bus cp, sets the corresponding phase shift U, and similarly on the bus cf. Next , following the sequence, first affect the control inputs of the F2 bus, set the frequency of the carrier wave, and then the bus frequency F. The values of the carrier wave frequencies in this

2 are the same, i.e. After power on

the clock generator 1 begins to form a constant frequency signal in the driver 2. The sinusoidal oscillations U and U- arrive at the analog inputs of the switch 5. At its control input comes either a pulse of the code sequence or a pause formulated in the driver 4. the passage of the oscillation U1, at the moment of arrival of the pause - U, j. Therefore, a FM signal is formed, and the moment of the beginning of the sinusoidal oscillation exactly coincides with the beginning of the pulse (or pause) of the code sequence, since they are formed from the same clock generator I.

The sequence of operator influence on tires F and tires Gg is similar for forming the FMM signal. When exposed to tires F. and F, it is necessary to specify the values of the carrier frequencies of the oscillations U., and U, T.e. F7 f, a F, f1t To form the DFM signal, the frequencies of the carrier frequencies are specified in the same sequence. The values of their phases are set by buses with /, and q and are equal to zero.

those. first on tire F., then

on the bus F, an FFM signal will be generated with a change in the values of the base frequencies U, and U. when they are generated. Moreover, the frequency change is made discretely and only at the moments of changing the code of the manipulating

sequences. If, for example, the manipulating sequence has the form 110001010 .., then the first, two characters are generated at a frequency f, the next three characters are generated at a frequency f5. Then, with each code change, the carrier frequencies will change, i.e. the sixth character is with the frequency f, the seventh f, the eighth f, the ninth f, etc. The magnitude of the frequency increment with each change is determined by the value of the frequency of the pulses entering the driver, 8 from divider 3. The initial phases are also set on the buses (and c. Thus, in this mode, an FMF signal is formed with adjustable parameters
