Abstract
The choice of signal propagation model in the implementation and analysis of the digital terrestrial television broadcast (DTTB) signal performance level in the Telecommunication Industry remains pivotal to Engineers and Scientists. The success recorded in the design and implementation of any DTTB system is attributed to the choice of the predicting model adopted. The aim of this investigation is to establish the efficacy of Okumura-Hata path-loss model in the application of DTTB network in Nigeria. The measured path-loss was relatively investigated with respect to Okumura-Hata and Free space propagation model using a simple drive test methodology. The Okumura-Hata model offered considerable RMSEs closer to zero which is satisfactory for high performance in terms of received signal strength when compared to the other propagation model. However, it implies that Okumura-Hata model could be preferred in the planning, design and implementation of DTTB network in Nigeria due to its superior performance in the predicted signal strength using digital video broadcast –terrestrial (second generation - DVB-T2) technology.
