Abstract
"PROCESSO DE ATUALIZAçãO DE UM REGISTRO DE DESLOCAMENTO DE CóDICO DE PSEUDO-RUìDO, PROGRAMA E PROCESSADOR PARA A REALIZAçãO DO PROCESSO". Expõe-se um processo de atualização de um registro de deslocamento de código de pseudo-ruído em um sistema de CDMA implementado por software a partir de um valor atual para um novo valor, incluindo representação de um polinómio de derivação como uma seq³ência binária de polinómio de derivação operando em "E" logicamente o valor de um último estágio do valor atual do registro com cada um dos bits da seq³ência de polinómio de derivação e operando em "XOR" logicamente o resultado da operação em "E" com o valor atual do registro.
