Abstract

métodos, sistemas e dispositivos para comunicação sem fio são descritos. um dispositivo sem fio, como um dispositivo em uma rede de área local sem fio, pode usar uma estrutura de quadro de rádio que inclui um campo de sinal de alta eficiência (he) e um campo de dados he para comunicações, por exemplo, através de espectro de radiofrequência compartilhada. um ou mais bits ou símbolos no campo de sinal hf podem ser ajustados para evitar uma relação de energia alta de pico para média (papr). em alguns casos, o alinhamento pode ser para um campo de sinal a (sig-a) ou sinal b (sig-b). em alguns exemplos, uma sequência de bit aleatório pode ser usada para preenchimento em um campo de sinal. em outros exemplos, bits podem ser invertidos ou misturados. ainda em outros exemplos, bits podem ser modulados e uma rotação de fase pode ser aplicada ao sinal correspondente.
