次最优的 meaning in Chinese
suboptimal
Examples
- We optimized to derive the merv input shaper and compare it to other input shapings . through the comparison , we can find out that the merv shaping yield the better performance than the others . we can also derive the hybrid input shapers if we simplify the optimal process
并应用merv (最小余振平均值)输入成型方法，以磁头定位系统为模型，通过数值优化过程求解出最优的merv输入成型器和次最优的混合输入成型器。 - And the experience of cutting sulphur emissions in america in the 1990s argues that second - best solutions can give way to the best : regulations on power stations were eventually superseded by a successful cap - and - trade scheme that cleared the stuff out of america ' s air
根据90年代美国减少硫排放的经验，美国人说有一个次最优的办法可以用来代替碳价，那就是一些列成功的限制贸易体制最终取代对发电厂的管制，美国空气中的那些脏东西就是这样消失的。 - The main works of the dissertation can be summarized as follows : 1 . by exploring the model of ds - cdma systems , the performances of the decorrelating multi - user detector and minimum mean square error ( mmse ) multi - user detector are studied . further , the performances of blind adaptive mud and adaptive mmse mud ( lms style ) with fixed step size and varied step size respectively are studied based on mmse linear detect algorithms
本文主要研究次最优的线性多用户检测技术，工作具体如下：从ds - cdma系统模型出发，研究了解相关多用户检测器和mmse多用户检测器的性能，并以mmse线性检测技术为基础，研究了变步长和固定步长的lms - mmse自适应多用户检测器和基于最小输出能量准则的盲自适应多用户检测器。
