代码说明:

  编写一个含QAM传输的发送和接收模块 1)分别采用复基带仿真和实带通仿真两种形式 a) 实带通仿真时, 载波频率为符号率的4倍 b)发端采用滚降系数0.5的根号升余弦滤波器 2)画出Eb/N0=15dB时的接收波形(收滤波前),取100个采样 3)画出发端输出的眼图和收端过匹配滤波后的眼图(画眼图时不加噪声) 统计误符号率和误比特率与Eb/N0的关系,画出曲线, 与理论计算的曲线相对比 (Prepare to send of one with QAM transmission and receiver module 1), respectively, the complex baseband simulation and the real band-pass simulation in two forms a) the real band-pass simulation, the carrier frequency used for the symbol rate of 4 times b) the originator roll-off factor of 0.5 root raised cosine filter, 2) draw Eb/N0 = 15dB when the received waveform (closing filter), take 100 samples) to draw the originator of the output eye diagram and income side of the eye diagram after the matched filter ( draw the eye diagram without noise) statistics symbol error rate and bit error rate and Eb/N0, draw a curve calculated with the theoretical curve compared)

    游需求分析婶予促进我目各地区的经济发展和文化交流都有着重要的意叉。由于旅游行业的。小样本,膏信息,不确定”性, 旅游市场可以看做是一个巨大的灰色系统。皋文竹对旅游需求同题进行了详细的研完,提出了基于灰色表镜理论的多元数学预测模型GM (1,N).合理分析诸多因素对旅游需求的综合影响,可以很好的解决此奏问题。同时。以北京地区旅游需求发展为倒,根据北京市旅游局平 的历年旅游统计数据,确定影响游客人数的因素并对其合理量化,应用GM(1,N)模型对最地的旅游需求进行预潮.井通过残盖检验,后戎 差检验手方法对谊模型进行分析.得到的攮测结晨比较准磅,未模型应用范田广泛,可以进行推广使用。(Travel demand analysis aunt I promote my head the region s economic development and cultural exchange has an important meaning fork.
