瑞利信道中的调制解调、信道估计simulink仿真
可自行转换成源代码
(1) 推导出单径瑞利信道中的BPSK相干解调的理论误码率性能，并画出比特信噪比与误码率的关系曲线。
(2) 在单径瑞利信道中，请设计一种时分的导引辅助的信道估计方法，用Simulink进行仿真，测量BPSK的误码率性能，画出比特信噪比与误码率的关系曲线，并与理论误码率曲线进行对比。

WiMAX和IEEE 802.16标准的宽带无线接入，是越…
WiMAX, or the IEEE 802.16 standard for broadband wireless access, is increasingly gaining in popularity as
a technology with significant market potential. This paper first provides an overview of the existing and
developing 802.16 standards and their key differences/applications. The PHY and MAC layers of a typical
WiMAX base station are then described. The associated implementation challenges faced by WiMAX
infrastructure developers, including performance/cost/flexibility trade-offs in the choice of silicon, are
clearly outlined. The paper then describes how FPGA-based system implementation can address these
challenges including the “accelerated time-to-market” requirement which is considered a key enabler for
early success in this market. As an example design, the physical layer implementation of the 802.16d
standard with Altera FPGAs and intellectual property (IP) is proposed.

虽然Windows下可视化开发工具如VC、Delphi、C＋＋ Builder等都有专用的定时器控件Timer，而且使用很方便，可以实现一定的定时功能，但最小计时精度仅为55ms，且定时器消息在多任务操作系统中的优先级很低，不能得到及时响应，往往不能满足实时控制环境下的应用。不过Microsoft公司在Win32 API函数库中已经为用户提供了一组用于高精度计时的底层函数，如果用户使用得当，计时精度可到1ms。这个计时精度、对于一般的实时系统控制完全可以满足要求。现将由C＋＋ Builder 4.0提供的重新封装后的一组与时间相关的主要接口函数（函数名、参数、功能与Win32 API基本相同）说明如下：
-visual development tools such as Visual C++, Delphi, C++ Builder and others all have dedicated Timer timer control, but it is convenient. can achieve a timing function, but only the minimum time of 55 ms accuracy. Timer news and multi-task operating system in the low priority that is not to respond in a timely manner, often fail to meet the real-time control environment applications. However, Microsoft Corporation in the Win32 API function has been to provide the user with a group for high-precision the bottom was a time function, if the user is properly utilized, time accuracy can be a ms. Accuracy this time, and for most of the real-time control system can meet the requirements.
