Abstract
"SISTEMA DE ACESSO MúLTIPLO POR DIVISãO DE CóDIGO DIRIGIDO A TRANSMISSOR UTILIZANDO DIVERSIDADE DE MULTIUSUáRIO PARA MAXIMIZAR CAPACIDADE DE TRANSMISSãO ENQUANTO PROVê DE FORMA JUSTA ACESSO AOS USUáRIOS". Um receptor distribuído dirigido por transmissor utilizando diversidade de multiusuário fornecida pela distribuição do receptor. A vantagem é tirada das variações não correlacionadas com o tempo na condição dos links de comunicação entre um transmissor comum e vários usuários. Quanto maior a variação na qualidade de um link específico com o tempo, maior o aumento no rendimento total do sistema. Uma métrica de programador (ou métrica de programador) representa a qualidade instantânea do link de comunicação entre cada usuário e o transmissor com relação à qualidade média do link. Alternativamente, a métrica de programador representa a condição instantânea do canal com relação ao rendimento médio dos dados através desse canal. A estação de transmissão comum utiliza a métrica de programador para comparar diretamente o desejo de se conceder acesso a cada canal com o desejo de se conceder acesso de canal um ao outro. Os usuários com links que possuem a métrica de programador mais alta recebem acesso aos canais.
