随着USB技术日趋成熟,USB开发者只需要关注顶层开发即可,这样虽然减少了工作量,但容易使开发者忽略USB基础理论与概念,导致的弊端在于开发者一旦遇到问题,往往不知如何解决。作者基于多年USB开发经验,针对当前很多USB开发者容易混淆的概念,进行深入浅出的剖析,针对枚举和重枚举的区别、不同启动方式的区别等问题,进行了归纳总结。本文从对比的角度分析问题,有助于开发者理清USB的工作机理。

程序用JAVA语言编写, 综合利用图结构和堆栈结构进行数据组织和处理. 可以进行正则表达式到NFA的转化, 并能用图形直观的表示. 对正则表达式有一些约定, 就是可以用单个字符表示输入, 也可以用 ‘ ‘ 连接起来的一串字符进行输入. 有基本的表达式以及由基本表达式构成的并置, 选择和重复的操作. 例: A|b*c ‘letter’*’digit’ 等都是合法输入. 还带有括号功能, 优先级

The JICQ is the bureau area which JAVA writes according to "Customer s Machine/Server"(C/S) mode message solid hour correspond by letter tool system, the system adopted the SQL Server2000 of Microsoft company as a backstage database, the system passes a JDBC interview database. The system is divided into the server procedure and customer s procedure two parts, server and customer adoption "Transmission Control Protocol"(TCP), connect a word (Socket) conjunction through a set, the adoption "User Datagram Protocol "(UDP) of the customer s, pass a data report a set to connect a word (DatagramSocket) establishment a conjunction. The system has customer registration, customer to register, increase good friend, delete good friend and send out and receive news etc. function.

Problem Statement You are given a string input. You are to find the longest substring of input such that the reversal of the substring is also a substring of input. In case of a tie, return the string that occurs earliest in input. Definition Class: ReverseSubstring Method: findReversed Parameters: string Returns: string Method signature: string findReversed(string input) (be sure your method is public) Notes The substring and its reversal may overlap partially or completely. The entire original string is itself a valid substring (see example 4). Constraints input will contain between 1 and 50 characters, inclusive. Each character of input will be an uppercase letter ( A - Z ). Examples 0) "XBCDEFYWFEDCBZ" Returns: "BCDEF" We see that the reverse of BCDEF is FEDCB, which appears later in the string. 1)

We address the problem of blind carrier frequency-offset (CFO) estimation in quadrature amplitude modulation, phase-shift keying, and pulse amplitude modulation communications systems.We study the performance of a standard CFO estimate, which consists of first raising the received signal to the Mth power, where M is an integer depending on the type and size of the symbol constellation, and then applying the nonlinear least squares (NLLS) estimation approach. At low signal-to noise ratio (SNR), the NLLS method fails to provide an accurate CFO estimate because of the presence of outliers. In this letter, we derive an approximate closed-form expression for the outlier probability. This enables us to predict the mean-square error (MSE) on CFO estimation for all SNR values. For a given SNR, the new results also give insight into the minimum number of samples required in the CFO estimation procedure, in order to ensure that the MSE on estimation is not significantly affected by the outliers.

Noncoherent receivers are attractive for pulsed UWB systems due to the implementation simplicity. To alleviate the noise effect in detecting UWB PPM signals, this letter proposes a simple yet flexible weighted noncoherent receiver structure, which adopts a square-law integrator multiplied with a window function.

北京大学ACM比赛题目 Write a program to read four lines of upper case (i.e., all CAPITAL letterS) text input (no more than 72 characters per line) from the input file and print a vertical histogram that shows how many times each letter (but not blanks, digits, or punctuation) appears in the all-upper-case input. Format your output exactly as shown.
