Modern cellular radio systems typically employ several thousands of transceivers simultaneously. An appropriate assignment of frequencies to cells can, in such a case, significantly suppress the intra-system interference. However, the process of frequency planning is a very complex and difficult task due to the fact that a great number of sometimes mutually opposing requirements should be satisfied. In the proposed algorithm, the optimisation of a nonlinear, multivariate and multicriterion interference function is realised in such a way to provide a very good frequency planning solution in acceptable short time. During the real radio system design, the performance of the proposed algorithm has been verified, both by simulation and in practice.","PeriodicalId":253344,"journal":{"name":"5th International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting Service.

Taking into account the high effective antenna surface, which is need for ensuring of the high spatial resolution, the peculiarity of these processes consists in disposition of the objects in Fresnel zone, where the antenna pattern is not formed yet. However, on the potential possibility to provide high spatial resolution, the near-zone imaging radar can be characterized by the presence of high distortions in the image formation channel. In this paper a characteristic of the distortions caused by beamforming features is described and the spread function of the channel of a single-position imaging radar was analytically established. The results allow one to reasonably create an optimal algorithm for spatio-temporal signal processing in single-position imaging radars.","PeriodicalId":253344,"journal":{"name":"5th International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting Service.
