Abstract

resumo patente de invenção: "sistema e método para modulação de amplitude em quadratura de desvio por multiplexação por divisão de frequência ortogonal". [0001] a presente invenção refere-se a um método para realizar modulação de amplitude em quadratura de desvio (oqam) por multiplexação por divisão de frequência ortogonal (ofdm) que inclui obter uma rajada de dados. o método inclui realizar modulação por filtragem circularmente convoluída ponderada na rajada de dados para produzir um sinal de saída. o método inclui, ainda, um primeiro dispositivo que transmite o sinal de saída para um segundo dispositivo sem fio. o segundo dispositivo sem fio recebe um sinal de entrada a partir do primeiro dispositivo sem fio e o segundo dispositivo sem fios realiza filtragem por desmodulação circularmente convoluída ponderada no sinal de entrada para produzir a rajada de dados.
