Abstract

"DISPOSITIVO DE COMUNICAçãO PARA UMA ESTAçãO BASE EM UM SISTEMA DE COMUNICAçãO DE ACESSO MúLTIPLO POR DIVISãO DE CóDIGO CDMA ASSìNCRONO, E PROCESSO DE COMUNICAçãO PARA UMA ESTAçãO BASE EM UM SISTEMA DE COMUNICAçãO CDMA". Um dispositivo de comunicação para uma estação base em um sistema de comunicação CDMA é descrito. Um gerador de código curto comum gera um código curto comum usado em comum por múltiplas estações base, um gerador padrão gera um padrão de modulação único, e um gerador de código de espalhamento longo gera um código de espalhamento longo único em períodos predeterminados. Um transmissor de canal específico espalha um sinal de transmissão em um canal comum específico com o código de espalhamento longo. Um inseridor de código curto comum modula o código curto comum com o padrão de modulação, punciona o sinal de transmissão no canal comum em períodos predeterminados e insere o código comum curto modulado no sinal de transmissão puncionado."COMMUNICATION DEVICE FOR A BASE STATION IN A MULTIPLE ACCESS COMMUNICATION SYSTEM BY DIVISION OF ASYNCHRONOUS CDMA CODE, AND COMMUNICATION PROCESS FOR A BASE STATION IN A CDMA COMMUNICATION SYSTEM". A communication device for a base station in a CDMA communication system is described. A common short code generator generates a common short code used in common by multiple base stations, a standard generator generates a single modulation pattern, and a long spread code generator generates a single long spread code at predetermined periods. A specific channel transmitter spreads a transmission signal over a specific common channel with the long spreading code. A common short code inserter modulates the common short code with the modulation pattern, punctures the transmission signal on the common channel at predetermined periods, and inserts the modulated short common code into the punctured transmission signal.
