临斯普斯卡共和国 CommunicationRS-232 是最常见的串行接口和船只作为在大多数 Windows 兼容的桌面计算机上的标准组件。RS-232 只允许一个发射器和一个接收器在每一行上。RS-232 还使用一种全双工传输方法。有些 RS-232 主板出售国家文书支持波特率达 1 Mbit/s，但大多数设备限于 115.2 kb/s。注意 RS-422/RS-485 接口不是大多数的 IBM 个人电脑上可用。RS-422 （EIA RS-422-A 标准） 是在苹果电脑上使用的串行连接。它提供一种机制达到 10 Mb/s 的数据传输。RS 422 发送每个信号同时使用两根电线增加的最大波特率和电缆的长度。RS 422 也为多点应用程序只有一个发射器发送到总线的高达 10 的接收器与相连，指定。Rs-485 是 rs-422 的超集和扩展的能力。RS 485 被迫解决 RS-422 多滴限制允许达 32 设备沟通通过相同的数据线。任何 RS — 485 总线上的奴隶设备能够沟通而不需要通过主设备的 32 奴隶的任何其它设备。由于 RS 422 是 RS 485 的一个子集，所有的 RS-422 设备可能由 RS 485 控制。这两个协议有多点的能力，但 RS-485 允许达 32 设备和 RS 422 的限制为 10。对于这两种通信协议，您应该提供你自己的终止。所有的国家文书 RS-485 板将与 RS 422 标准工作。

A 2x2 multiple-input multiple-output (MIMO) architecture using dual-polarized antennas (DPAs) is considered with orthogonal frequency division multiplexing (OFDM). The performance of DPAs is evaluated for adaptive polarization (AP) transmission techniques in time-varying multipath channels impaired by polarization mode dispersion (PMD) and polarization-dependent loss (PDL). AP transmission techniques considered include power gain maximization, polarization dispersion minimization for interference avoidance, polarization multiplexing with waterfilling, and a suboptimal multiplexing strategy that enables direct recovery of the polarization multiplexed streams, thereby simplifying the design of the receiver. Measured time-varying dual-polarized channel realizations from mobile-to-mobile experiments are used to estimate the capacity, diversity, and interference avoidance performance of the adaptive approaches.

　调试对于软件的成败至关重要，正确使用恰当的调试工具可以提高发现和改正错误的效率。本书详细介绍了 3种调试器，gdb用于逐行跟踪程序、设置断点、检查变量以及查看特定时间程序的执行情况， ddd是流行的 gdb的 gui前端，而 eclipse提供完整的集成开发环境。书中不但配合实例讨论了如何管理内存、理解转储内存、跟踪程序找出错误等内容，更涵盖了其他同类书忽略的主题，例如线程、客户 /服务器、gui和并行程序，以及如何躲开常见的调试陷阱。(Debugging for is vital to the success of the software, the proper use of appropriate debugging tool can improve the efficiency of discovery and correct mistakes. Book introduces in detail three kinds of debugger, GDB for tracking procedures, set breakpoints, line by line check variables and checking their specific time execution of DDD is popular the GDB GUI front-end, and eclipse provides a complete integrated development environment. The book not only cooperate with examples to discuss how to manage the memory, understanding, memory dump and trace program error, more covers other similar books ignore themes, such as threads, client/server, GUI, and the parallel program, debugging and how to avoid common pitfalls.)

说明：  此程序可以对信号进行小波分解和重构，并且分解的频率按从高到低排序(This program can decompose and reconstruct the signal by wavelet transform, and the decomposition frequency is sorted from high to low.)

基本下拉菜单的创建与消息响应，VC++精选编程学习源码，很好的参考资料。(The basic menu creation and message response, VC++ select learning programming source code, a good reference.)

说明：  matlab读取dat文件，带字符的那种，用于读取dat并把数据分开，(Matlab reads the dat file)

这是DTMB标准的发送对的MATLAB建模，包括多种信道模型和多种调制方式，可以进行灵活切换。(This is the DTMB standard to send the MATLAB modeling, including a variety of channel models and a variety of modulation, can be a flexible switch.)
