discriminator detection meaning in English

鉴频器检测

As we have introduced a multilevel decision method with discriminator detection to improve the error rate performance , the deducing and analyzing for this method are present in this article . the theoretical error rate and the monte carlo simulation result are showed in figure to compare the system error rate performance affected by different premodulation filter
在系统误码仿真中引入了一种有助于改善误码性能的鉴频加多电平判决的解调方法，文中对此方法也进行了详细的推导和分析，并给出根据此方法计算出的误码理论值，结合系统误码性能的蒙特卡罗仿真值，对比分析各种预调滤波器对系统误码性能的影响。
