Abstract

"PROCESSOS DE REDUçãO DE INTERFERêNCIA DE CO-CANAL EM UMA COMUNICAçãO DE RáDIO CELULAR E DE AUMENTO DO NúMERO DE USUáRIOS EM UM SISTEMA DE COMUNICAçãO VIA SATéLITE DE FEIXE MúLTIPLO, E, SISTEMA DE COMUNICAçãO DE RáDIO CELULAR". Um esquema de carregamento fracionado é utilizado para aperfeiçoar a eficiência espectral de um sistema celular, e portanto o aumento do número de usuários que o sistema pode suportar. O esquema de carregamento fracionado permite apenas que uma fração do número total de canais de comunicação disponíveis dentro de cada célula seja utilizada simultaneamente. Dessa forma, cada célula é deliberadamente carregada de forma insuficiente para operar pelo menos em sua capacidade total. O carregamento insuficiente das células individuais reduz a eficiência espectral dentro de cada célula. Entretanto, o carregamento insuficiente de cada célula significa que ainda existirão menos usuários interferentes em qualquer momento determinado de forma que a interferência do co-canal seja reduzida. Essa redução na interferência de co-canal permite que a distância de reutilização entre as células de co-canal seja reduzida aumentando assim a reutilização das freq³ências por todo o sistema resultando em um aumento da eficiência espectral no sistema como um todo.
