查询词典 noncoherent

It is shown that, the impact of IPI due to the pre-filter is insignificant to noncoherent receiver, and there exist different optimal pre-filter passband widths for different channels and input SNRs.

结果表明，在信道模型CM1~CM4下，前置滤波器产生的多径分量干扰平均来说对其输出能量的影响很小，并且一般来说存在一个最佳的滤波器带宽值。

It is stated that multipath is closely related with observation environment and receiver performance. In more detail, receiver is classified as coherent delay loop and noncoherent delay loop by its operation. Their tracking properties for GPS signals are determined by discriminator curve.

GPS 中的多路径效应是在一定的观测环境下产生的，不同的 GPS 接收机所受到的多路径效应影响也有所不同，因此，除观测环境外， GPS 接收机内部工作机理与多路径效应的产生是密不可分的。

In addition, the results demonstrate that the ratio of coherent topic-shift types to noncoherent topic-shift types would be lower in conversations of close social distance than in conversations of far social distance.

在前测中，我们还采用《汉语恭维语应用咨询表》分别调查学习者在使用汉、英两种语言表达恭维语及应答方面的情况。

To reduce the receiver complexity,a differential space-frequency transmit diversity scheme was developed with a noncoherent detection method based on the frame structure of the time domain synchronous-orthogonal frequency division multiplexing system.

在采用相干检测方法的发射分集方案中，进行信道估计需要付出很高的代价，为了降低接收端的实现复杂度，根据时域同步正交频分复用系统结构的特点，提出了差分空频发射分集及相应的非相干检测方法。

In the second part, emphasis is put on the multiple capacity of orthogonal coded spread-spectrum multiple access system with coherent and noncoherent demodulations. The multiple access capacities of uncoded system and error -correcting coded system are compared. The capacity improvements which result from the use of diversity techniques are also studied.

第二部针对正交码扩频多址系统中多址容量的问题，分析比较了采用纠错码和不加纠错码时OC-SSMA系统的多址容量，并研究了分集技术的采用对OC-SSMA系统容量的提高，指出在信息速率及码片速率相同的条件下，正交码扩频系统的性能明显优于常规扩频系统。

Simulations in flat-faded application scenarios show that, the subspace method can achieve the same diversity order with the coherent reception, and outperforms the noncoherent decoder in existence with multiple successive space-time codes being decoded jointly.

平坦衰落信道环境中的仿真表明，子空间方法能够实现和相关接收相同的分集增益；当多个连续的空时码联合解码时，其性能优于现有的非相关解码方法。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
