粒子滤波 等数十种工具箱（基于MATLAB）(particle filter TOOLBOX)

说明：  二相相移键控（BPSK）是用二进制基带信号（0、1）对载波进行二相调制。BPSK是最简单的PSK形式，相移大小为 180°，又可称为2-PSK。在群点聚集的地方，其实都不是非常有关系，在该图像中，群点分布在水平轴上的0°和180°上。由于BPSK使用严重的失真致使解调器作出错误的判断，所以该调制方式是所有PSK中最强的。但它只能以1bit/symbol调制而不适合高数据率应用情况。 (bpsk modulation)

上传一个将正弦函数通过Delta-Sigma调节器转换成正负一的脉冲信号。并分别激励同一系统，得到良好的一致输出(Upload a sinusoidal function by Delta-Sigma modulator converts a signal of positive and negative pulse. And separately driven in the same system, to obtain a good coincidence output)
