WIFI下客户端和服务端互相通信
使用softAP实现多方聊天通讯的例子源码，首先把多部手机连接到一个局域网中，在一个手机上安装服务端，然后服务端会自动显示一个可访问的IP地址并等待客户端连接，在其他手机上安装客户端，输入服务端显示的IP地址点击连接就可以与服务端进行连接，不需要改动源码里面的任何东西，亲测有效。

今年上半年我为现公司一款流量计产品编写的上位机Modbus通讯程序（下位机程序也是我用C编写的，由于受到法律许可限制，在此不能上传，不过在将来我会把设计思路传上共享），包括自创的Modbus协议的Delphi实现及其完整调用，还有一份我编写的该产品的完整的Modbus协议说明书，非常有参考价值。-First half of this year the company I am now prepared a flowmeter products PC Modbus communications procedures (the procedures are under-bit machine I use C prepared, because of license restrictions by law, can not upload here, but I will in the future design ideas Chuan-share), including self-Modbus protocol Delphi to achieve their full call, there is also a preparation of the product I am a complete Modbus protocol specification, a very good reference material.

opnet电池模块
opnet中zigbee协议下经常需要进行节能研究，需要添加电池模块。
ZigBee网络是资源受限的网络, 集中表现在电池能量、数据整合能力、存储空间及通信带宽等非常有限。终端节点采集的原始数据直接传送到路由节点是现在普遍采用的方法，但由于原始数据信息冗余性的存在会浪费有限的电池能量和通信带宽；频繁的信道竞争也会降低信息收集的效率。物理层和MAC层是ZigBee协议射频芯片硬件实现的，所以数据融合只能与网络层和应用层相结合。由于数据融合和网络层相结合带来的跨层的问题给协议栈的实现带来很多困难。

We investigate the case of independent Rayleigh faded paths between antenna elements and find that with
high probability extraordinary capacity is available. Compared to the baseline n = 1 case, which by Shannon’s
classical formula scales as one more bit/cycle for every 3 dB of signaltonoise
ratio (SNR) increase, remarkably
withMEAs, the scaling is almost like n more bits/cycle for each 3 dB increase in SNR. To illustrate how great this
capacity is, even for small n, take the cases n = 2, 4 and 16 at an average received SNR of 21 dB. For over 99
of the channels the capacity is about 7, 19 and 88 bits/cycle respectively, while if n = 1 there is only about 1.2
bit/cycle at the 99 level. For say a symbol rate equal to the channel bandwith, since it is the bits/symbol/dimension
that is relevant for signal constellations, these higher capacities are not unreasonable. The 19 bits/cycle for n = 4
amounts to 4.75 bits/symbol/dimension while 88 bits/cycle for n = 16 amounts t
