1. INVESTIGAÇÃO TEÓRICO-EXPERIMENTAL SOBRE O COMPORTAMENTO DO DESVANECIMENTO RÁPIDO NAS LIGAÇÕES DE MICRO-ONDAS EM VISIBILIDADE / THEORETHICAL AND EXPERIMENTAL INVESTIGATION OF FAST FADING IN LINE-OF-SIGHT MICROWAVES LINKS
The purpose of this work is to present a mathematical model to interpret theoreticallly the statistical behavior of deep fades in line-of-sight microware paths. The previous theories are discussed and compared to the known experimental data. A simple model is used to obtain a theoretical dependence of the fades deepth with the path roughness. The results sho

2. COMPARATIVE ANALYSIS OF TRANSMISSION SYSTEMS USING COAXIAL CABLE AND MICROWAVES LINE-OF-SIGHT / ANÁLISE COMPARATIVA ENTRE SISTEMAS DE TRANSMISSÃO EM CABO COAXIAL E ENLACES RADIOELÉTRICOS EM VISIBILIDADE
This work examines two telecomunications systems which are usually used in the establishment and operation - the transmission system by coaxial cable and the transmission system by microwaves line-of-sight. Both are divided in their campontent parts, which calculation in surveyd. After the surveying of costs of both system, one can define a relating magnitud

3. ESTUDO SOBRE A CONFIABILIDADE DE SISTEMAS DE TELECOMUNICAÇÕES / A STUDY ON THE RELIABILITY OF TELECOMMUNICATION SYSTEMS
This work deals with the performance os line-of-sight microwave links as a function of equipment behavior (failure rate and reposition time) and the propagation caracteristics (fading). The studied models correspond to usual system configurations and several numerical results are presented to ilustrate the theoretical formulation. The equipment reliability i
