接收端

The error signal is smoothed by loop filter, then it is used to change the control register of interpolator and decimator: The proposed algorithm can track the frequency shift of sampling clock. The algorithm is simulated in both AWGN and multipath fading channel.

这种方法在发送端相邻载波间采用差分QPSK调制，在接收端利用QPSK的差分解调信号获得同步误差信号，从而获得关于OFDM符号同步和采样钟同步调整的算法，其特点是无需专门的同步导频信号。

The design of the sampling rate conversion sub-module includes that of interpolator,decimator and shaping filter,during the course of which,the researcher choose different methods,comparing their corresponding spectrum masking performance of the transmitter as well as EVM and PER performance of the receiver respectively to choose an appropriate shaping filter.

在设计当中，作者选择了不同的方法，通过比较发送端的频谱屏蔽性能以及接收端的误差向量幅度性能和误包率性能选取合适的成形滤波器。

Within the amended algorithm, semi-optimistic locking mechanism in CIAO is replaced by token mechanism, and Receiver-reliable multicast based on the father node number is proposed to enhance robustness of system. Entities and avatars in scene are organized the structure of tree. Its father node number is augmented in each entity's ESPDU (Entity State Protocol Data Units). The receiver adjusts the structure of local scene tree according to the node number of package received.

西南交通大学博士研究生学位论文第11页改进了 CIAO（Collaborative Immersive Architectural layout）中实体组同步控制算法，用令牌机制替换CIAO中半乐观锁机制，并提出了基于父节点记录的收端可靠多播算法，即在每个实体的 ESPDU（Entity State Protocol— Data Units）中增加父节点的节点号，接收端根据父节点的节点号调整本地场景树的结构。

In addition to the signal strength is probabilistic vibration, and it follows Gaussian normal distribution in signal space.

此外，在讯号空间的观点来看，固定一对传送端和接收端的距离，各种讯号强度出现的机率的是呈现Gaussian Normal Distribution，因此利用RSSI (Received Signal Strength Indicator)的测量距离的技术是不准确的。

However it is not suitable for multi-and high-speed Ad Hoc networks for the incurrence of serious over-interference area and poor performance in such environment. A scheme is proposed to solve this problem, which includes Adaptive-RTS and Adaptive-CTS at both sender and receiver side.

我们提出了一种适合多速率高速Ad Hoc网络的自适应RTS／CTS握手机制，来解决多速率MAC协议在Ad Hoc网络中的大干扰区问题和性能低下问题，该自适应过程包括发送端的自适应RTS机制（Adaptive RTS，A-RTS）和接收端的自适应CTS机制（Adaptive CTS，A-CTS）。

Compared to a disabled TextBox, it is legible yet conveys a change in the state of the control.

发送端和接收端可分别在不同机器上，只需对方的IP地址。

As a result, retransmission signal error rate characteristics are improved on the receiving side by despreading this code division multiplexed signal using the same plurality of spreading codes as on the transmitting side, and selecting or combining the despreading results with the greatest correlation power thereamong.

其结果，在接收端使用和在发送端相同的多个扩频码解扩该码分复用信号，选择其中相关功率最大的解扩结果或者是加以合成就能够提高重发信号的差错率特性。

As the true capacity formula for blind-CSI in both transmitter and receiver is hard to obtain, we derive its independent upper bound instead, and establish a close-form expression of the independent bound for any memory order $M$.

由於，在传送端与接收端均无「频道状态资讯」的情况下，管道传输极限的计算相当困难，因此我们转而探讨其「独立上界」。

By utilizing the unitary matrix, the transmitter decouples the input signal into spatial orthogonal beam directions with the matched filters in beam directions in the receiver, and the gain obtained by each data block can be equivalent to the sum of the projection from the channel matrix to the corresponding beam directions. Beam selection is adopted to maximize the minimum gains of all the blocks, which can improve the system diversity gain efficiently.

发射端采用酉矩阵将数据映射到空间正交的波束方向上，通过接收端波束方向上的匹配滤波，各数据分块所获得的增益为信道矩阵在其波束方向上的投影之和，波束选择通过最大化所有数据分块最小增益，从而有效地提高了系统的分集增益。

The new mechanism ameliorates the method of information exchanging between the server end and client end.

它改进了发送端与接收端之间的信息交互方式。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
