Investigation of Rain Effects over DTH and BER Modeling
Abstract
The Direct-To-Home (DTH) TV has immensely spread in last five years. The service is very swift and the quality of audio and video is also very high. The cost of DTH set (the small dish, set top box) is very nominal, so anybody can afford it. The main advantage of DTH is that it can be installed anywhere in remote areas. The only bottleneck is the heavy rain and windy weather. During those times, the signal reception becomes week, sometimes it become unavailable. This paper analyzes the rainfall rate of a remote place in heavy raining zone and satellite signal reception in a DTH TV. The paper mainly discusses about the relationship of rain intensity with the signal reception. The bit error rate (BER) is analyzed in different weather conditions. Also the paper focuses on the BER Modeling. The scope of the work is 950-2150 MHz satellite analog downlink signal and heavy raining zone. It is seen that the signal reception is week during windy heavy rain, when Doppler Effect is much higher.
