Digital-baseband-system
数字基带系统将数字信号从时域上看时数字滚降,需要画出滚降前后的波形展示出来。频域上带宽变化了。输入滤波器之前的波形与采样判决之后的波形。采样判决前的频谱。
采样判决后的码型。
2、眼图(采样判决之前的眼图)(信噪比大眼图清晰)
3、误码曲线,(横坐标时信噪比,纵坐标时误码率)
4、Arfa变化对误码特性的影响,变好还是变差(变好),眼图清晰度变化(清晰),传递函数的带宽的变化。(带宽越大)(1.Digital baseband system point of view the digital signal from the time domain when the number of roll-off, you need to draw the waveform displayed before and after the roll-out. The frequency domain, the bandwidth change. Input filter and sample ruling before the wave after wave. Sample pre-judgment spectrum.
Sampling pattern after the verdict.
2, the eye diagram (eye before sampling decision) (SNR big eye clear)
3, the error curve (abscissa when the signal to noise ratio, bit error rate when the vertical axis)
4, Arfa impact of change on BER performance, get better or worse (getting better), change of eye-definition (clarity), the transfer function of the bandwidth changes. (The greater the bandwidth))

说明: 在MATLAB中编写程序,利用三边定位算法对未知节点定位。已知在平面坐标系内,三个锚节点的坐标分别为(50,100)、(0,0)和(100,0),在0≤x≤100,0≤y≤100的区域内随机产生10个未知位置的节点(其横、纵坐标均为上述范围内的随机数)。
利用三边定位算法
对这10个未知位置的节点进行定位(计算其坐标值),并与其真实位置(随机产生的坐标值)进行比较(MATLAB three-side positioning algorithm)

SCA:用于解决优化问题的正弦余弦算法
说明: 用于求解单目标优化问题的正弦余弦算法。
SCA创建多个初始随机候选解决方案,并要求它们使用基于正弦和余弦函数的数学模型向外波动或朝向最佳解决方案。几个随机和自适应变量也被集成到该算法中,以强调在不同的优化里程碑中探索和利用搜索空间。
压缩包包括:发表的论文、优化算法代码、优化工具箱。(Sine-cosine algorithm for solving single objective optimization problems.
SCA creates multiple initial random candidate solutions and requires them to use mathematical models based on sinusoidal and cosine functions to fluctuate outward or towards the best solution. Several random and adaptive variables are also integrated into the algorithm to emphasize exploring and utilizing search space in different optimization milestones.
Compression packages include: published papers, optimization algorithm code, optimization toolbox.)
