摘要: Embodiments of the present invention provide a method to produce a modulation signal comprising combining at least two modulation signals, for example, BOCs or derivatives thereof, having portions (chip or a number of chips) thereof with respective relative phases or states ({++,−−} and {+−,−+}) selected such that the average of a plurality of said portions at least reduces cross spectral terms of the composite complex spectrum of said at least two modulation signals.
摘要翻译: 本发明的实施例提供一种产生调制信号的方法,包括组合至少两个调制信号,例如BOC或其衍生物,其具有相应相对相位或状态的部分(芯片或多个芯片)({++ , - }和{+ - , - +}),使得多个所述部分的平均值至少减少所述至少两个调制信号的复合复谱的交叉光谱项。
