Abstract

In this paper we analyzed possible capacity gains in transition from DVB-T to DVB-T2 standard. We compared minimum C/N ratio needed for quasi error free reception of DVB-T and DVB-T2 systems with similar transmitting parameters currently used in Croatia. C/N was calculated using simulations developed in Matlab for those standards, in three commonly used channel models: Gaussian, Ricean and Rayleigh. Results show bandwidth increase of about 63% without significant increase of the minimum C/N. By using newer compression techniques and statistical multiplexing in large pools, it can be concluded that up to 10 times more TV channels (with the same quality) can be transmitted in the same occupied frequency bandwidth.
