    • A ceiling value can be established (505) for a sum of peak power for a first baseband signal (330) and a second baseband signal (332). No correlation needs to exist between the power peaks of the baseband signals (330, 332). A detection can occur (510) indicating that a sum of the baseband signals (330, 332) has a peak power exceeding the ceiling value. This detection can result in modifications of both the first baseband signal and the second baseband signals. Each is modified by: first modifying each signal so that the sum of the signals is less than the ceiling value (515), to filter the results with a root raised cosine function (520), to window clip the filtered results (525), and to filter the clipped results using a root raised cosine filter (525). The modified signals can be amplified (e.g., by amplifier 342), and the amplified signals can be transmitted by a multicarrier transmitter (e.g., transmitter circuitry 206).
    • 对于第一基带信号(330)和第二基带信号(332)的峰值功率的和可以建立上限值(505)。 在基带信号(330,332)的功率峰值之间不需要存在相关性。 可以发生表示基带信号(330,332)的总和具有超过最大值的峰值功率的检测(510)。 这种检测可以导致对第一基带信号和第二基带信号的修改。 每个被修改为:首先修改每个信号,使得信号的总和小于上限值(515),以用根升余弦函数(520)过滤结果,以筛选滤波结果(525), 并使用根升余弦滤波器(525)来过滤截取的结果。 修改的信号可以被放大(例如,由放大器342),并且放大的信号可以由多载波发射机(例如,发射机电路206)发射。
