The analysis of experimental investigation of spatial signal processing of a microwave band for a signal-of-interest with modulation QAM-M extraction (M=64, 128, 256) from a wanted signal radiation source against interference from another radiation source for the case when bands and polarization type are the same, but the radiation source angular position is different, are presented. These results...
The unused possibilities for signal coordinate determination of a radiation source (RS) with phase m?nipulation (PM) in the existing mobile communication systems are shown. The usage of sparse antenna arrays and a radiation source location in the Fresnel region of the antenna array for this case are examined. The approaches and scheme realizations of phase radio systems for coordinate determination...
Possibilities of digital radio relay stations (DRRS) “Komplex MG” application to increase theoretical and practical skills of Institute of Telecommunication Systems of NTUU “KPI” students are shown. The approaches for laboratory tests concerning the main elements of DRRS during transmission of the real radio signals are presented.
A phase distance measurement technique is reviewed, which increases difference phase shift accuracy measurement in microwave system with a short distance between antennas.
A well-known space-time processing (STAP) criteria are analyzed and the interference rejection algorithms with STAP for antenna systems with wide radiation pattern are proposed.
Practical methods for the measuring devices creation which allow determining new information parameter in the microwave systems - difference of the phase differences (double phase difference) are shown.
Theoretical possibility of jammer and signal sources' discrimination procedure is shown by using requirements for radiation sources discrimination system (SDS).
