The conceivable algorithm for upgrading the DVB-T2 network
Abstract: The article is concerned with the issues of the optimisation of the existing digital TV broadcasting networks that do not require any significant expenses. The algorithm of the software complex has been developed enabling one to perform automatic searching of the optimal network configuration. The verification of the prototype of the software complex has been successfully performed. The paper is a continuation of the previous work of authors.
Key words: single-frequency DVB-T network, service zone, Longley-Rice model, target functions.
