Abstract

resumo método de envio/recepção de sinal, aparelho e sistema correspondente a invenção refere-se a um método para o envio / recepção de um sinal, e um aparelho e um sistema correspondente. o método inclui: a execução de uma constelação de mapeamento de um fluxo de dados para obter um sinal de mapeamento; realizar uma filtragem prejudicial sobre o sinal de mapeamento para converter o sinal de mapeamento para um sinal filtrado a partir de um sinal de banda estreita, o pré-filtro é um filtro com resposta de impulso finita, a largura de banda do sinal filtrado a partir do sinal de banda estreita sendo menor do que o sinal de mapeamento e o sinal filtrado do sinal de banda estreita ser um sinal de taxa de transmissão; de acordo com o sinal filtrado do sinal de banda estreita, realizar uma forma de onda de moldagem, a fim de obter um sinal de moldagem; realizar uma conversão digital / analógica do sinal de formatação para converter um segundo sinal de moldagem para obter um sinal analógico para um transmissor de sinal envia o sinal analógico. através da conversão de um mapeamento de sinal de banda larga num sinal de banda estreita filtrada por um filtro, o transmissor da solução permite que o sinal filtrado para passar sem um conversor digital / analógico problema que também é de banda estreita, o que reduz o perdas causadas pela largura de banda insuficiente de um dispositivo.
