Optimization methods for interferences reduction between mimo radar and system of cellular communication

Telecommunication Engineering

For the Radar MIMO, the Uniform Layer Antenna permit to beam the propagation on any specific angular. The interference with the cellular network could not convenient for that indeed about the envelope of the Radar. In this fact, the spectrum sharing is a new approach to solve this problem. The projection on Null Space could reduce the interference by inserting signal to transmit with the value of this projection. The solver of this problem could translate by a nonlinear problem without constraints. The choice of the most optimization algorithm could be problematic without having any algorithm to evaluate and select one of them because the random behavior of the interference’s noise could be more advantages or more disadvantage than the other methods. Le author’s contribution consists to create new criteria for the performance of the envelope by basing on the surface occupied of the transversal schema of the propagation and creation any selection algorithm for the beamforming of best resolution about FACE or Finite Alphabet Constant Envelope BPSK/QPSK on condition to null space. The BADS, NM, PSO are the candidate choose for the solver optimization. The output of the algorithm contains the algorithm of resolution and the binary signal to transmit for having a good deviation of the beamforming and capabilities to resist with the interference.
