接收端

Charging handle is made in the form of dual sliders located at either side of receiver.

充电手柄是由在任的在接收端位于双滑块形式。

Signal source data arises by the general purpose computer, output with serial means high speed through PCI bus line, sink hardware system need not any changes.

信号源数据由通用计算机产生，通过PCI总线以串行方式高速输出，接收端硬件系统无需任何改变。

After convolutional encoding , the data is reordered by the interleaver. At the receiver , the data pass through deinterleaver for the purpose of dividing possible consecutive error bursts into inconsecutive code , so it can be corrected by convolutional decoding. Matrix interleaver with CPLD is designed , because it is convenient to program. Considering various matrix interleaver , an all - purpose matrix interleaver is designed. You can ap2 ply it to your own project only altering initial parameters.

交织编码在3G系统中已经大量使用，数据通过卷积编码后进行分组交织，在接收端完成反交织，将连续误码分散成非连续误码，从而使得误码在纠错允许的范围内得到纠正； CPLD 具有方便的在线编程功能，可以用来实现交织编码；考虑到矩阵交织器的多样性而设计的通用矩阵交织器，只须通过修改一些参数值即可实现不同的交织器，大大节省了设计时间。

First, mathematical foundation of synchronization, i.e. the theory of parameter estimation is introduced. Then, DA/DD or NDA timing synchronization methods based on the ML estimation of timing parameter are presented. They are all widely applied in actual digital communication systems. Interpolation theory in digital signal processing has application in timing synchronization, which makes the sampling clock independent of the timing control so that timing adjustment is realized completely through digital disposal. The issue of interpolation in timing synchronization is discussed.

首先，介绍了定时同步实现的数学基础，即信号参数估计理论；从定时参数的最大似然估计出发，介绍了基于数据辅助的定时同步方法和基于非数据辅助的定时同步方法，他们在实际的数字通信系统中均有广泛应用；论文探讨了数字信号处理中插值理论在定时同步中的应用，它使得接收端的采样时钟独立于定时控制，定时调整完全通过数字处理方法得以实现。

The uplink synchronization mechanism is using the invariance of the preamble which is also known to the base station.

我们在接收端的上行同步处理机制是利用上行传输资讯的不变性，直接对收到的信号作相关性的运算。

In high speed wideband wireless communications, the duration of channel's impulse response is about hundreds of symbol periods, which causes the convergence speed of linear blind equalizer to be much slower.

摘要高速宽带无线通信中，多径传输信道可能导致几百个符号间的相互干扰，这使得接收端的线性盲均衡器的收敛速度极其缓慢。

This paper is to study the low noise amplifier, the primary stage of the RF/microwave receiver, The function of LNA is to amplify the uV vohage signal received by antenna.

低噪声放大器是对来自天线的微伏级信号进行放大的射频接收端的放大模块。

To detect possible transmission errors, the receiver determines whether the received number of "1" bits is even or odd depending on the parity agreed.

为了检查可能传输中出现的错误，接收端将检查接收到的1的位的奇偶是否符合奇偶校验。

This technique is based on offsetting the bias voltage of MZ modulator from its inflection point.

这个方法同时能够抑制在传输系统上所产生的非线性失真，也可以提高接收端的载波杂讯比。

It would be nice to let them be on the receiving end for a change!

它会很好，让他们成为对接收端为改变！

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
