Description
Устройство работает следукщам образом .The device works in the following way.
Прин тый сигнал с комбинированной частотной и относительно фазовой манипул цией поступает на вход перемно сител 2, а затем в полосовой фильтр 4. Здесь с помощью обратной св зи по решению осуществл етс фазова разманипул ци принимаемого сигнала. Результирующий только частотно-модулированный сигнал подаетс на частотный детектор 9. Полученный результат частотной демодул ции поступает на второй формирователь 6 импульсов , который подаетс к получателю информации. .Прин тый сигнал с комбинированной частотной и относительно фазовой манипул хшей, пройд первый полосовой фильтр - 3, поступает на первый вход фазового детектора и по методу сравнени пол рностей на второй вход фазового детектора 10 подаетс опорное частотно-манипулированное колебание с выхода, второго полосового фильтра 4. Полученный результат фазовой демодул ции, пройд через первый формирователь 5 импульсов , подаетс на второй вход перемножител 2 (обратна св зь по решению ) и на вход декодера 1, с выхода которого информаци подаетс другому получателю.The received signal with a combined frequency and phase shift keying is fed to the input of alternator 2, and then to the bandpass filter 4. Here, using feedback, the solution is used to phase out the received signal. The resulting only frequency-modulated signal is fed to a frequency detector 9. The resultant frequency demodulation is fed to a second pulse shaper 6, which is fed to the receiver of information. The received signal with a combined frequency and phase shift keying, passed the first bandpass filter - 3, is fed to the first input of the phase detector and, using the polarity comparison method, to the second input of the phase detector 10 is fed the reference frequency-manipulated oscillation from the output of the second bandpass filter 4. The result of phase demodulation, passed through the first shaper 5 pulses, is fed to the second input of the multiplier 2 (feedback on the solution) and to the input of decoder 1, from the output of which the information is fed To another recipient.
Таким образом, положительным эффектом от использовани предлагаемого устройства по сравнению с известным вл етс повышение помехоустойчивости приема дискретной информации передаваемой методом фазовой манипул ции , за счет исключени паразитной фазовой манипул ции и потерь помехоустойчивости , возникаюищх при частотной демодул ции сигнала с комбинированной частотной и относительно фазовой манипул цией, а также упрощение приемного устройства.Thus, the positive effect of using the proposed device as compared with the known is to increase the noise immunity of receiving discrete information transmitted by the phase shift keying method, by eliminating spurious phase shift keying and noise immunity losses arising from the frequency demodulation of the signal with a combined frequency and phase shift key. as well as the simplification of the receiving device.
