Invention relates to radio engineering, namely to devices which perform coherent demodulation of signals with Minimum Shift-Keying (MSK-signals), and can be used in receiving systems of satellite communication and receiving systems of digital radio communication, which operate in conditions of complex signal-noise situation or in conditions of limited radio frequency resource. The coherent demodulator of non-orthogonal MSK signals contains: seven multipliers, four reference generators, six low-pass filters, four subtractors, two limiter amplifiers, two solving units, one inverter. The technical result is coherent reception (separation) of non-orthogonal MSK signals, increase of their noise immunity at reception and increase of subscriber capacity of the network twice.
Invention relates to radio engineering, namely to devices that perform coherent demodulation of signals with minimal frequency manipulation, for which the English name Minimum Shift-Keying is adopted, in an abbreviated version and further in the text - MSK signals. Such signals are usually used in a complex signal-interference environment.
