1. Estudo Analítico e numérico de um enlace digital de comunicação via satélite em condição orbital geo-estacionária / Analytical and numerical analysis of a digital communication geostationary satellite link.
The links of satellites are affected by propagation conditions and distortions that are generated by devices. The propagation losses as well as the passive components attenuation are very simple to analyze, but many calculations involved with the complete link demand to discover the carrier to inter-modulation ratio. This work presents an innovative set of e

2. ANÁLISE DE INTERFERÊNCIAS ENVOLVENDO SISTEMAS DE COMUNICAÇÃO QUE UTILIZAM SATÉLITES NÃO-GESTACIONÁRIOS: CASO EM QUE PARCELAS DE INTERFERÊNCIA SÃO MODELADAS POR VARIÁVEIS ALEATÓRIAS / INTERFERENCE ANALYSIS INVOLVING COMMUNICATION SYSTEMS THAT UTILIZE NON-GEOSTATIONARY SATELLITES: MODELING SINGLE-ENTRY INTERFERENCE TERMS RANDOM VARIABLES
The objective of this work is to extend the use of the Analytical Method for assessing the interference involving non-geostationary satellite networks to situations where the interference entries from the various satellites in a given Constellations are modeled as statistically independent random variables. The analysis of this type of situation requires a l

3. AN ANALYTICAL METHOD TO DETERMINE THE STATISTICAL BEHAVIOR OF THE INTERFERENCE GENERATED BY SATELLITE NETWORKS THAT USE NON-GEOSTATIONARY SATELLITES: EXTENDING THE METHOD TO REPEATED-TRACK SATELLITES / MÉTODO ANALÍTICO PARA A DETERMINAÇÃO DAS ESTATÍSTICAS DA INTERFERÊNCIA EM REDES DE COMUNICAÇÕES QUE UTILIZAM SATÉLITES NÃO GEOESTACIONÁRIOS: EXTENSÃO AO CASO DE SATÉLITES COM TRAJETÓRIAS REPETITIVAS
This work presents the theoretical description and implementation of an analytical method for the evaluation of the statistical behavior of the interference produced or received by elements of a non-GSO network. This method is based on the knowledge of the probability density function of the position of one of the satellites of the non-GSO constellation (ref

4. DETERMINING THE STATISTICAL BEHAVIOR OF THE INTERFERENCE GENERATED BY SATELLITE NETWORKS THAT USE NON-GEOSTATIONARY SATELLITE: NUMERICAL IMPLEMENTATION OF THE ANALYTIC METHOD / DETERMINAÇÃO DO COMPORTAMENTO ESTATÍSTICO DE INTERFERÊNCIAS ENVOLVENDO REDES DE COMUNICAÇÕES QUE UTILIZAM SATÉLITES NÃO GEOESTACIONÁRIOS: IMPLEMENTAÇÃO NUMÉRICA DO MÉTODO ANALÍTICO
This thesis presents the numerical algorithm description for the implementation of the analytical approach to assess interference in environments involving NGSO satellite networks proposed in [1]. For completeness purposes it also included to analyze the interference sensitivity to system and network parameters without the reliability problems and the excess
