Abstract

The GE-06 Agreement “On planning the terrestrial digital broadcasting services in parts of Region 1 and 3, in the frequency bands of 174-230 MHz and 470-862 MHz” has been based in the DVB-T system of transmission. Most of the signatory countries of this agreement use or are going to use the most advanced digital terrestrial technology such as DVB-T2. One of the main advantages of DVB-T2 comparing with DVB-T is an increased size of SFN networks, which is closely related with guard interval or inter-transmitters distances. To achieve the maximum size of DVB-T2 SFNs, it is important to find optimal parameters of DVB-T2 networks. But even though the GE-06 Plan gives opportunities to implement DVB-T2 there are some limitations on using all its benefits. One of these limitations is the availability to increase the distance between transmitters because changes in the location of any transmitter require long and intensive coordination with neighboring countries. The aim of this paper is to investigate the optimal DVB-T2 networks configuration for two existing SFN networks in Albania with the purpose to achieve maximum SFN size without adding transmitters or changing the location of existing transmitters.
