Abstract

"BUSCA DE SISTEMA CANDIDATO E SOFT HANDOFF ENTRE FREQuêNCIAS EM UM SISTEMA, DE COMUNICAçãO MóVEL DE MúLTIPLAS PORTADORAS". A presente invenção consiste de uma estação móvel compreendendo: um transmissor para a transmissão de sinais de emissão a partir da estação móvel; e um receptor para a recepção de sinais recebidos, o receptor acoplado ao transmissor e possuindo N sub-receptores, em que N é um número inteiro maior que um e cada um dos N sub-receptores pode ser independentemente sintonizado em uma freq³ência desejada. A presente invenção inclui também um sistema de comunicação sem fio compreendendo: (1) uma pluralidade de estações base, em que cada uma das estações base transmite sinais através de pelo menos uma dentre uma pluralidade de freq³ências; e (2) uma pluralidade de estações móveis, pelo menos uma dentre a pluralidade de estações móveis compreende: (a) um transmissor para a transmissão de sinais para pelo menos uma dentre a pluralidade de estações base; e um receptor acoplado ao transmissor para recepção de sinais provenientes de pelo menos uma dentre a pluralidade de estações base, o receptor possuindo N sub-receptores, em que N é um número inteiro maior que um e cada um dos N sub-receptores é independentemente sintonizado em uma freq³ência desejada.
