Performance Evaluation of different Path Loss Models for Broadcasting applications

In this paper we highlighted the performance evaluation of different path loss model and envisage the most suitable model for plane area in northern region of India i.e. border district of Punjab and Jammu. In this paper we compared the different path loss propagation models with measured field data and investigated the appropriateness of the model which gave us results closer to measured (field) data. In the present work we used many path loss models for comparative analysis. This research paper presents a comparative analysis of six empirical path loss models with respect to measured data for plane area in state of Punjab and Jammu (India). The preferred six models under investigation are COST- 231, Hata, Okumara, Free space model, Extention of Hata model and Hata Davidson model. For investigations and analysis purpose, firstly the measured field data has been taken in the Gurdaspur (State: Punjab) by using the 100w FM radio transmitter and transmitting antenna height of 45m, and in second case we used 10 kw FM transmitter at Kathua (State: Jammu) i.e. situated in bordering area of Punjab and Jammu at transmitting antenna height of 100m with fixed receiving antenna height of 4 meters. On analyzing the different results we found that Cost-231 model is best suited for plane area in norhen region of the border district of Punjab (India). Although in our investigations Hata Davidson model shows better results than the extension of Hata model for longer distances, but the mean square error of cost - 231 was found to be minimum as compared to other models.
