Abstract

1 / 1 resumo “mã‰todo de busca pela presenã‡a de um sinal, produto de programa de computador, unidade para receber um sinal, e, estaã‡ãƒo” a invenã§ã£o refere-se a um mã©todo (50) para buscar a presenã§a de um sinal usado com uma largura espectral prã©-definida ∆b em uma banda de multiplexaã§ã£o com uma largura espectral maior que ∆b, que compreende as etapas de: (51) calcular um sinal de frequãªncia representativo de uma densidade de energia espectral na banda de multiplexaã§ã£o; (54) calcular um sinal nã£o usado pela filtragem do sinal de frequãªncia por meio de um filtro adequado para eliminar todos ou alguns dos sinais com uma largura espectral igual ou menor que ∆b; (56) calcular um sinal da razã£o de energia representativo da razã£o entre o sinal de frequãªncia e o sinal nã£o usado; e (57) comparar o sinal da razã£o de energia com um valor limite prã©-definido. a invenã§ã£o tambã©m refere-se a um produto de programa de computador, a uma unidade receptora e a uma estaã§ã£o (30) de um sistema de telecomunicaã§ãµes digitais (10) que compreendem uma unidade receptora como esta.
