Abstract

Предлагается способ получения спектральных пустот при передаче сигналов по электрической сети. Предложенный в изобретении способ позволяет передавать сигналы по электрической сети с соответствующей спектральной плотностью мощности с возможностью ее адаптации к существующим правилам и эффективного введения спектральных пустот в процесс передачи. Изобретение отличается тем, что для создания упомянутых пустот регулируют мощность на одной или нескольких несущих сигнала ортогонального частотного уплотнения, используют обратное дискретное преобразование Фурье по меньшей мере с 1024 точками (если обратное дискретное преобразование Фурье является комплексным) или по меньшей мере 2048 точками (если обратное дискретное преобразование Фурье является вещественным) и используют окно, на которое умножает символы, передаваемые с течением времени.
