应用背景应用于通信系统信号的调制解调实例，通过systemview软件搭建通信系统仿真平台，给出了信号的调制解调过程及波形具体形式，为与通信实际环境相关，采用高斯噪声模拟通信信道。关键技术SystemView主要用于搭建通信系统平台，采用了软件中的相关器件实现信号的调制及发射。采用低通滤波等得到基带信号，然后采用单刀双掷开关等器件完成判决，实现解码。

接收机,利用C8051F330编写的接收解码程序-receivers use C8051F330 prepared to receive the decoding process.

串口编程,主要用于测试串口发送命令控制 开发工具为VC6.0-Serial programming, mainly for testing serial port to send commands to control development tools for VC6.0

通过MP（代表其中一个P口）的高4位来控制，AA`BB`-4，5，6，7脚。12细分，没行数组里面分4对，每对数第一个加到P口控制电流方向，第二个数控制通电时间。正转AA`-BB`-A`A-B`B,数组由1到12行的读取，反转B`B-A`A-BB`-AA`,数组由12到1行的读取。参数POWER表示电机启动还是不启动，DIRECT参数表示方向，SPEED表示速度等级，每项通电时间用数组中的植/SPEED。本程序没考虑要走多少步的情况，调用一次就走一步。-Through the MP (on behalf of one of P I) of high 4 to control, AA `BB`-4,5,6,7 feet. 12 segments, no line inside the sub-array of four pairs, each of the P added to the number of the first current direction of population control, the second time the number of control power. Are transferred AA `-BB`-A `AB` B, the array from 1-12 line read, reverse B `BA` A-BB `-AA`, array 12-1 by the line read. POWER express motor parameters activated or not activated, DIRECT express direction parameter, SPEED express speed grades, each time power array sik/SPEED. This procedure did not consider how to go step-by-step situation, call a step away.

iPhone手机SDK编程参考书，不仅叙述详细，而且还有许多例子代码，是学习iPhone SDK编程的一本好书。-iPhone, SDK programming reference books, not only described in detail, and there are many examples of code, is to learn from iPhone SDK programming, a good book.
