正交带 meaning in Chinese

perpendicular band

Two multi - band ( all band ) sampling schemes are also proposed for software radio . based on the quadrature sampling , uniform sampling and high order sampling techniques , we investigated how to compute and choose a reasonable sampling frequency
从理论上分析了软件接收机以正交带通采样、一阶均匀带通采样、高阶采样等方法为基础，如何计算、选择合理的采样频率。
The sampling technology is also being explored which including lowpass sampling , quadrature sampling and direct passband sampling and the setting of a / d , sampling rate , data acquisition and selecting filtering parameters . the implementation of each technique is also being discussed
分别对低通采样、正交带通采样和直接带通采样技术中有关a d在系统中的位置、采样率的确定、信息获取和滤波参数选取等问题进行系统论述，并讨论了各自的技术实现问题。
