Abstract

The Amazon has the world's largest tropical forest and about the half of all freshwater in the world. The construction of the wire guided communications systems is denied byinternational environment regulation because the Amazon is a worldwide protected area.Satellite communications systems represents the best option to provide communications services to the Amazonian region. However, the quality and availability of the signals in Ka band are seriously degraded by various climate phenomena, especially the rain [1]. The footprint of the Venezuelan Satellite has a large coverage service area over the Amazonian. The rain fade leads to the degradation of the link quality with unacceptable error rate and lower system capacities. In order to overcome this problem, and keep the link properties in normal conditions (clear sky conditions) the diversity concept can be used. The diversity principle is based on the transmission of multiple copies of the same signal. The copies of the signals can be combined at the receiver or be selected the best copy of the signal. The research aim is is modeling the channel attenuation for Ka band and simulate the performance of the Venezuelan Satellite with several receive antennas similar to a Single Input Multiple Output (SIMO) system. The main purpose, is to analyze the system capacity and bit error rate of BER with lower values of Signal to Noise Ratio (SNR) and compare the results with Single Input Single Output (SISO) performance.
