Abstract

trata-se de sistemas e métodos de comunicação sem fio em que os dispositivos sem fio são adaptados para implantar a seleção de forma de onda adaptativa, em particular, para comunicações de onda milimétricas. por exemplo, a operação de acordo com as modalidades pode estabelecer o uso de um projeto de forma de onda que minimiza a razão entre potência de pico a média (papr), como a multiplexação por divisão de frequência de única portadora (sc-fdm), assim como um projeto de forma de onda que fornece maior eficiência espectral, como multiplexação por divisão de frequência ortogonal (ofdm), para cenários que não são limitados por potência e a papr maior é aceitável a seleção adaptativa de forma de onda pode se basear implicitamente em um ou mais parâmetros ou pode se basear na sinalização explícita. os ditos parâmetros são snr, inúmeras portadoras de componente se a agregação de portadora estiver presente, e siso/mimo. em particular, a ofdm é preferencial no caso de mimo, agregação de portadora ou snr alta.
