搭建BPSK+编码+交织仿真通信链路
说明: 搭建 BPSK+编码+交织仿真通信链路,仿真分析在不同信道条件下的不同译
码算法的误比特率性能。基于 matlab,搭建 BPSK+卷积编码+交织通信收发链路,
仿真参数如下: 1) 信源比特速率: 100 b R kbps = 2) 卷积编码:码率为 1/2,生成多项式为(561,753) 3) 译码方式:维特比译码(硬判决译码、软判决译码(8 比特量化)) 4) 交织:行列交织,交织器深度为 100bit,宽度为 10; 5) 仿真点数:106 1. 在 AWGN 信道下,仿真并绘出该系统在硬判决和软判决(3bit 量化)两
种译码方式下的信源误比特率曲线,并进行分析。 2. 设定某种交织器结构,在单径瑞利衰落信道( 100 d f Hz = )下,采用理 想信道估计,仿真并绘出该系统在有无交织、不同译码方式(硬判决和 软判决)时,在不同 0 b EN下的信源误比特率曲线,并进行分析。 3. 改变交织器结构,选择三种不同的交织深度(自行决定),在单径瑞利衰 落信道( 100 d f Hz = )下,仿真并绘出该系统在不同交织长度时,在不 同 0 b EN下的信源误比特率曲线,并进行分析。(Build a BPSK + encoding + interleaving simulation communication link, and analyze the different translations under different channel conditions
The bit error rate performance of the code algorithm. Based on MATLAB, BPSK + convolutional coding + interleaved communication transceiver link is built,
The simulation parameters are as follows: 1) source bit rate: 100 b r Kbps = 2))

VC++数据曲线动态绘制显示类
说明: MFC编程 实现数据绘制成曲线。经兄弟推荐最终决定用两个控件MCSCOMM与TeeChart来完成此任务。MCSCOMM控件时vc自带的串口控件,TeeChart Pro是一个强大的VCL图表组件,支持上百种2D和3D图表风格,并提供40多个数学和统计函数、无限制的轴和22个调色板(MFC programming realizes data plotting into curves. After recommendation by brothers, we finally decided to use two controls, MCSCOMM and TeeChart, to accomplish this task. TeeChart Pro is a powerful VCL graphics component that supports hundreds of 2D and 3D graphics styles and provides more than 40 mathematical and statistical functions, unlimited axes and 22 palettes.)

ModbusPollCS
某智能设备公司开关量采集系统(Modbus RTU),很不错哦!对于该类设备基本上都可以通用,只是“寄存器地址”不一样。我就参照该源程序写了一款SOS应急呼叫系统、酒店客房插卡取电、退房呼叫系统等。保证原创,独一无二。(A smart device switch acquisition system (Modbus RTU), very good, oh! Can be generic, such equipment is basically just not the same register address. I refer to the source Admission card, write a SOS emergency call system, hotel rooms, check out the call system. Guaranteed original, unique.)
