转换门限 meaning in Chinese

switching threshold

To make use of the maximum signal margin with the maximum scanning distance tolerance , the switching threshold should be set at the mid - way point between the background and mark signals
在使用具有最大扫描距离偏差的最大信号边限时，转换门限应该设置在背景与标识信号的正中间？
Furthermore , analytical model for adaptive coded modulation is proposed , through which channel snr switching thresholds with the aim of throughput maximization of adaptive coded modulation are obtained with the method of lagrange , and then the average throughput performance of the adaptive system is obtained
通过建立自适应编码调制研究模型，本文还应用拉格朗日函数法得到了使自适应编码调制系统吞吐量性能最大的信道信噪比转换门限，进而得到自适应系统的平均吞吐量性能。
