Abstract

"SUPORTE DE DETECçãO DE MULTIUSUáRIOS NO "LINK" INFERIOR". Onde o sistema de comunicação duplex de divisão de tempo sem fio que utiliza acesso múltiplo de divisão de códigos possui uma estação básica e equipamentos de usuário. O sistema comunica-se através da utilização de lampejos de comunicação. Cada lampejo de comunicação possui um código de canalização exclusivo e um código de metade de trajeto. Cada código de metade de trajeto é mapeado em um conjunto de pelo menos um código de canalização. Para cada lampejo de comunicação a ser transmitido em um espaço de tempo a partir da estação básica, é determinado o código de metade de trajeto mapeado para o código de canalização daquele lampejo. Os lampejos de comunicação são gerados e transmitidos no espaço de tempo. Cada lampejo possui o código de metade de trajeto determinado para o seu código de canalização. O equipamento do usuário recebe os lampejos e determina cada código de metade de trajeto recebido. O equipamento do usuário determina os códigos de canalização dos lampejos de comunicação transmitidos com base, em parte, em resultado da determinação de cada código de metade de trajeto recebido.
