Abstract

método de transmissão de dados, método de recepção de dados, dispositivo de modulação e dispositivo de desmodulação. usando pontos de sinal arranjados circularmente obtidos rearranjando uma parte de pontos de sinal rearranjados em um formato retangular ou um formato cruz, a potência média do sinal e energia de pico do sinal são reduzidas parar melhorar as características de distorção não linear. é provido um método de mapeamento de bits no qual um valor médio de uma distancia hamming em termos de uma porção de bits inferiores especificada entre pontos de sinal adjacentes é pequena, e uma distância euclidiana entre pontos de sinal nos quais as porções de bits inferiores atribuídos à mesma coincidem entre si se torna máxima. aplicando código de correção de erro somente à porção de bits inferiores, um método de transmissão de dados excelente em características de taxa de erros de bits é provido enquanto suprimindo uma taxa de expansão de banda.
