Prediction Model for Broadcasting Propagation in Urban Area

摘要

This study proposes an optimization of the path loss propagation model for prediction digital terrestrial television broadcasting in urban area Southern of Thailand. The measurement areas are considered both Songkla and Surathani Provinces that we conducted the data collection of the received signal radio broadcasting in 4 channels (510-790 MHz). The optimization of the path loss propagation model is based on Least Square (LS) method. The statistical results such Hata path loss model is optimized as a comparison with others model. We confirm that the proposed method provides for a data processing suitably in a prediction path loss model.
