Description: 写一个MATLAB程序，实现4个时间同步的CDMA用户的仿真，其中每个用户都使用长度为L=31的不同的Gold序列。每个用户都采用它们代表的Gold序列的二进制（+-1）调制。每个用户的接收端将这个复合的CDMA接收信号相关，而这个复合的信号都在它们各自的序列上受到AWGN的污损（基于按码片相加）。在N=10000信息比特下，仿真估值并画出作为SNR的函数的CDMA通信系统的差错概率。-Write a MATLAB program, the realization of the four time synchronization of the simulation of CDMA users, including the length of each user for use of the L = 31 different Gold sequences. They are used for each user on behalf of the Gold sequence of binary (+-1) modulation. Each user' s receiver will receive the composite CDMA signal, and this composite signal in the sequence of their respective defaced by the AWGN (additive based on the chip by). Information in the N = 10000 bits, the simulation value and draw as a function of SNR of the CDMA communication system the probability of error.

Description: 电子标签防碰撞是RFID 系统中一个关键问题。在射频识别系统中．当阅读器作用范围内有多个标签同时向阅读器发送数据时，会产生冲突，必须采用一种防碰撞算法解决这种冲突。在分析典型的二进制及动态二进制防碰撞算法基础上，采用了一种新的防碰撞算法。经实验证明，该算法能有效解决射频识别系统中多目标识别的防碰撞问题。-Tag anti-collision RFID system is a key issue. In the radio frequency identification systems. When the reader within the framework of the role of multiple tags simultaneously send data to the reader, it will create conflict, you must use a anti-collision algorithm to solve such conflicts. In the analysis of a typical binary and dynamic anti-collision algorithm based on the binary, using a new anti-collision algorithm. The experiments show that the algorithm can effectively solve the radio frequency identification system, multi-target recognition of the anti-collision problem.

Description: orthogonal variable spreading factor (OVSF) is an implementation of Code division multiple access (CDMA) where before each signal is transmitted, the spectrum is spread through the use of a user s code. User s codes are carefully chosen to be mutually orthogonal to each other.
These codes are derived from an OVSF code tree, and each user is given a different, unique code. An OVSF code tree is a complete binary tree that reflects the construction of Hadamard matrices.

Description: BREW 是美国高通公司（QUALCOMM）为无线数据应用程序开发和执行提供的
通用接口平台，主要支持CDMA 手机，最新也可以支持GSM 手机。BREW 提供了一套应
用程序接口（API），设备制造商和开发人员可以随时对运行环境进行扩展，提供应用程序
需要的各种附加性能模块。本文通过研究BREW 事件处理机制，理解了BREW 事件驱动模
型。在了解BREW 程序执行过程的前提下，分析了事件驱动处理中需要注意的问题并给出
了相应的实例，最后根据最新发展趋势介绍了触摸屏事件处理。
关键词：BREW；事件驱动；事件处理；单线程
中图分类号：TP319-BREW (Binary Runtime Environment for Wireless) is an application development platform created by
QUALCOMM, originally for CDMA mobile phones, but GSM is now also supported. The main
advantage of BREW platforms is that the application developers can easily port their applications. In
this paper, according to a deep research on BREW event handling mechanism, we will have a better
understanding of the BREW event-driven model. After understanding the implementation of BREW
program we analysis the problems we should take good care of in the event handling process. Finally
there is a brief introduction about the touch-screen event handling according the new trend nowadays.
Keywords: BREW event-driven event handling single-threaded
