The object of research is the technological processes: the choice of nazemngo digital television broadcasting, frequency spatial planning service. Objectives of the study presented technological processes: the choice of digital terrestrial television broadcasting, a frequencytion of territorial planning sluzhby.Metody research: the deduction - the implementation of information retrieval, system-ray structure analysis - the choice of topics, tasks, research and technology, mathematical and geometrical analysis - the development of design drawings and creating mathematical models; apparatus investigations of diffraction and dissemina-tion of radio waves; mathematical modeling - the study of technological processes; mathematical interpretation of research results. Scientific novelty of the results: is that the purpose of research is achieved by the author obtained new scientific and reasonable results, which together solve the task of networking digital radio and television broadcasting, which is essential for science and practice of countries with difficult terrain, in particular for Syrian Arab Republic. As a result of research: Improved recommenda-tion on the use of MCE DVB-T standard in the frequency bands III, IV and V, given that the planning of digital terrestrial televi-sion broadcasting in the Syrian Arab Republic as a full member of the International Agreement "Geneva 2006" on planning the digital terrestrial television and broadcasting in Regions 1 and 3 of the International Telecommunication Union, at this stage is one of the most urgent tasks. I received the subsequent development of radio wave propagation model, based on the recommenda-tions MCE R.1546-3, as the current internationally recognized methodology for determining the field strength, it forms the basis of the calculations. The detailed analysis of the basis for planning the broadcasting services based on propagation models, which are based all calculations and the need to quantify associated with planning. First obtained by the method of planning the digital terrestrial television and radio stations for countries with difficult terrain. Improved classification and summarized the main fac-tors that influence the network planning of digital terrestrial television; developed generalized criteria that optimize the frequency-spatial planning of digital broadcasting in a complex terrain. For the first time the quantitative data that show the dependence of the required percentage of the territorial coverage of the parameters of antennas, power transmission equipment; was the subsequent development of the issue of non-hierarchical and hierarchical modes of DVB-T, which allows solving the task in construct-ing the network, estimated noise immunity of DVB-T as a function on the type of modulation used when using non-hierarchical model. The practical significance of the results is that, thanks to them to ensure greater efficiency of technological processes of choice of digital terrestrial television broadcasting, frequency and spatial planning service. The approach to planning the digital terrestrial television and radio stations is of general significance and can be applied in a wide range of additions and implementa-tions. These quantitative assessments will focus in making the specific technical solutions aimed at creating a national network of digital television and radio veschaniya.Privedennye assess the environmental effect of radio propagation in the conditions prevail-ing in the Syrian Arab Republic, is the basis for practical planning and television broadcasting service in this country and coun-tries with similar geographic conditions. Results of mathematical simulation gives quantitative kos interpretation of the possible options for implementing a network of digital terrestrial broadcasting.The results of the thesis are introduced and used in the educatinal process the department of television and radio broadcasting educational and research inctitute of radio, television electronics,Odessa National Academy of Telecommunications.Popov.
