The immunity of non-coherent and coherent reception of a signal DQPSK in the conditions of influence of PSK, a harmonic interference or Gaussian noise

Konstantin Lozhkin, Alexander Stitsenko

Abstract


By the method of making the indicators of output elements obtained according to the average probability of correct reception in optimum incoherent receiving-solver symbol and binary element no fading DQPSK signal when exposed to PSK or harmonic interference from the signal-to-noise ratio. The analysis of these dependencies and comparison of optimal noise immunity of incoherent and coherent of receivers with DQPSK signal with PSK, a harmonic interference and Gaussian noise.
