代码说明:

  M=4的PSK通信系统进行蒙特卡罗仿真 仿真BPSK和4PSK调制信号在高斯信道下的性能,并与理论分析结果相比。 (1) 画出两条性能曲线,一条是根据理论平均错误概率画出,另一条是仿真曲线; (2) 程序的基本流程:信源产生信息比特、调制、将调制信号送入信道(产生高斯白噪声的程序)、接收端检测、将检测结果与信源原始信息比较计算误符号率和误比特率; (3) 在给定信噪比下,第二步需多次重复,以得到一个平均错误概率; (4) 信噪比范围:BPSK(0dB – 10dB),4PSK(0dB-14dB),间隔是1dB 也可在BER=10-6左右终止。 (5) 信噪比计算 SNR=10log(Es/N0)=10log(REb/N0).

  • ESPRIT
    ESPRIT是“Estimating signal parameters viarotational invariance techniques”的缩写,含义是“借助旋转不变技术估计信号参数”,它是由Roy[221等人于1986年提出的另一种基于子空间的DOA估计方法。 应用领域   侧向定位 信号处理 思想   ESPRIT的思想在于,将传感器阵列分解为两个完全相同的子阵列,两个子阵中每两个相对应的阵元具有相同的平移,即要求阵列具有平移不变性,每两个位移相同的阵元匹配成对。所幸的是实际中许多阵列满足这个条件,比如等距直线阵。(ESPRIT is "Estimating signal parameters viarotational invariance techniques" acronym, meaning "With ESPRIT estimation of signal parameters", it is by Roy [221, who in 1986 proposed DOA estimation method based on subspace another. Applications Lateral positioning signal processing Thinking ESPRIT thinking that the sensor array is divided into two identical sub-arrays, each of the two sub-arrays of two corresponding array element has the same translation, which requires an array with translation invariance, the displacement of each of the two identical arrays yuan matching pairs. Fortunately, many of the actual array satisfy this condition, such as equidistant linear array.)

    (不错的一篇文章,已被EI收录)模型预测控制(model predictive control,MPC)路径规划算法适用于三维动态环境下的无人机(un-manned aerial vehicle,UAV)路径规划;动态贝叶斯网络(dynamic Bayesian network,DBN)能够有效推理战场态势,对无人机进行威胁评估。针对威胁尾随无人机时的路径规划问题,构建 DBN 威胁评估模型,将 UAV 在战场环境中的威胁态势用威胁等级概率表示,与 MPC 路径规划算法相结合,得到基于 DBN 威胁评估的 MPC UAV 路径规划算法。通过多组仿真分析表明,在三维动态环境下,特别是威胁尾随无人机时,基于 DBN 威胁评估的 MPC无人机路径规划算法可以得到有效的无人机路径。(The model predictive control (MPC)path planning algorithm can solve the problem of dynamic unmanned aerial vehicle (UAV)path planning.Dynamic Bayesian network (DBN)is an effective tool for rea-soning and threat assessment.Considering the problem of path planning when the dynamic threat tags the UAV,the MPC path planning algorithm combined with DBN threat assessment is presented,which used the threat lever probability to describe the threat situation.A group of simulations demonstrate the efficiency of MPC three-dimensional dynamic path planning algorithm for UAV based on DBN threat assessment especially when the dynamic threat tags the UAV.)
