Description: 功率谱估计的应用范围很广，在各学科和应用领域中受到了极大的重视。在《现代信号处理》课程中讲述了经典谱估计和现代谱估计这两大类谱估计方法；经典谱估计是基于傅立叶变换的，虽然具有运算效率高的优点，但是频谱分辨率低同时旁瓣泄漏严重，对长序列有着良好的估计。为了克服经典谱估计的缺点，人们开展了对现代谱估计方法的研究。现代谱估计是以随机过程的参数模型为基础的，有最大似然估计法、最大熵法、AR模型法、预测滤波器法。现代谱估计对短序列的估计精度高，同经典谱估计互为补充。在认真学习了现 代谱估计方法后，我选择了现代谱估计中的AR模型法的仿真作为题目。下面给出AR模型的相关理论和仿真实现。-Power Spectral Estimation of very extensive, in all disciplines and fields of application of a great deal of attention. The "modern signal processing" on the curriculum of classical and modern spectral estimation spectrum is estimated that the two types of spectrum estimation method; Classical spectrum estimation is based on Fourier transform, although high computing efficiency advantages, but also low-resolution spectrum Sidelobe serious leakage of long sequences have good estimates. In order to overcome the classic shortcomings of the spectrum estimation, there have been a pair of modern spectral estimation methods. Modern spectral estimation is the random process model parameters based on the maximum likelihood estimation, maximum entropy method, AR model, forecast filter. Spe

Description: LibTorrent is a BitTorrent library written in C++ for *nix, with a focus on high performance and good code. The library differentiates itself from other implementations by transfering directly from file pages to the network stack. On high-bandwidth connections it is able to seed at 3 times the speed of the official client.
The client uses ncurses and is ideal for use with screen or dtach. It supports saving of sessions and allows the user to add and remove torrents.

Description: ARM7硬件说明与开发
The ARM7 is a low-power, general purpose 32-bit RISC microprocessor macrocell for use in application or
customer-specific integrated circuts (ASICs or CSICs). Its simple, elegant and fully static design is
particularly suitable for cost and power-sensitive applications. The ARM7’s small die size makes it ideal for
integrating into a larger custom chip that could also contain RAM, ROM, logic, DSP and other cells.-ARM7 hardware illustrated and developed The ARM7 is a low-power, general purpose 32-bit RISC microprocessor ma crocell for use in application or customer-spe cific integrated circuts (ASICs or CSICs).

Description: 本设计通过按S3、S4和S5功能键实现对时间的调整。
其中，S3键为小时/分钟调整选择键；S4键为加1键；S5键为减1键。
时间调整的具体实现过程如下：
S3键功能是判断是否进行时间调整。当按一次S3键后，进入小时调整。再通过按S4、S5键进行对小时的具体调整；当按二次S3键后，进入分钟调整。再通过按S4、S5键进行对分钟的具体调整，直至和当前北京时间一直为止。
然后根据按下S2功能键的情况判断是否显示时间。若是，则将当前时间数据送8155经LED显示器显示。
进行传送。其优点是传送速度快，缺点是数据有多少位，就需要多少根传输线，适合于近距离传输-adopted by the design of S3, S4 and S5 function keys to achieve the right time to adjust. Among them, S3 Key to hours / minutes adjustment selection key; S4 a key to the Canadian bond; S5 key to a reduced bond. Time to adjust to the realization process is as follows : S3 key function is to judge whether the time to adjust. When S3 according to a bond after entering the hour adjustment. Passed by the S4, S5 Key for hours on the specific adjustments; When the second by S3 Key, enter minute adjustments. Passed by the S4, S5 key for the specific right-minute adjustments, and until the current Beijing time has been so far. S2 according to press the function keys of the judgment showed. If so, the current time data will be sent to 8,155 by the LED display shows. Transmitted. The advantage is spe
