The paper first introduces the selected mapping method for the reduction of the peak-to-average power ratio of OFDM signals, and a method for improving SLM using m-sequence is put forward.
在研究用选择性映射降法降低OFDM系统峰均功率比的基础上，提出了用m序列对SLM方法进行改进。
Accordingly, by varying a duty ratio of power through a phase control using a temperature variation slope of a heating roller, a fine control of a fixing system can be performed.
因此，通过使用加热辊的温度变化斜率的相位控制来改变功率的占空比，可执行对定影系统的精细控制。
It has big power range, high transmission efficiency and transmission ratio correctly, long using life, etc, but from the failure parts, gear is the most vulnerable parts of the fault.
它具有功率范围大，传动效率高，传动比正确，使用寿命长等特点，但从零件失效的情况来看，齿轮也是最容易出故障的零件之一。
