Abstract:

The review of algorithms for shaping and processing of radio signals with controlled coupled between quadrature components (RСCQC) developed in Department of Radio control and Communications of Ryazan State Radio engineering University was introduced. The mathematical formulation for complex envelope of RСCQC and the mathematical equations for spectral power density and for bit error rate of these signals were produced. The methods of shaping T-OQPSK, FQPSK, GMSK and unknown radio signals based on RСCQC were considered. The main results of synthesis of 16-ary RСCQC and results of synthesis of spreading code sequences used in adaptive communication systems with RСCQC were produced. The suggestions of the RSCQC use for increase structural immunity of perspective communication systems were made.
