Rain Effect on Satellite Communication’s Link Design in regions of P, N, and K with Logic design implementation

There have been many investigations taken place how rain attenuation can affect satellite communications. The main concern is to how to implement the link design margin that meets the cost requirement. In this study, the author applied the logic design such courting register to satellite transponder while investigating rain attenuation effect on satellite communications. The investigation takes place in some parts of Brazil, Paraguay, Argentina countries, and Atlantic ocean; representing for P, N, and K regions. The specifications for uplink and downlink were identified for P, N, and K regions. The parameters of the technical satellite design, in particular DBS-TV system, were determined based on specifications of uplink and downlink. The link budgets were evaluated for uplink and downlink criteria in the regions. The link availability and outage in rain were determined in order to evaluate the capability of the system. The results are conducted with double converter QPSK DBS-TV transmitter for the uplink Earth station, double converter QPSK DBS-TV transponder of the satellite, and downlink Earth station receivers on the regions of P and N. The investigations are for 16 Ku-band transponders in order to evaluate Bit Error Ratio, carrier power per thermal noise power ratio, link outage for appropriate coding gain and implementation margin.
