贝叶斯滤波如卡尔曼滤波，粒子滤波等，给定一线性或非线性动态系统，用已知的观测数据和动态向量求后验概率。该资源是贝叶斯滤波器的C++类库，里面包括卡尔曼滤波（kalman filter）、粒子滤波（particlefilter）等。希望对想用C++实现滤波算法的同学有所帮助！

因特殊的业务需要，某些电话交流需要在第三方的监视下进行，假定某电话交流由甲乙丙三方发起，丙为监听控制方，当甲开始说话时，丙可以不允许乙听，并且开始录音，当甲说完时，丙确定是否可以让乙听，如可以。给乙放录音，当乙说话时，重复以上操作。-because of special operational needs, some telephone exchanges in the surveillance of third parties under the assumption that a telephone exchange was launched by the tripartite B, and C to monitor the controlling party, began to speak when the A, B C can not listen, and began recording at the end when A and C to determine whether or not they can B listen, if we can. B recordings to release, when the B words, to repeat the operation.

现有数字信号自动调制识别方法大多只适用于无记忆信号，如PSK、ASK、FSK信号等。将有记忆 信号(MSK信号)和无记忆信号一起考虑，提出了一种改进的数字信号自动识别方法。该方法采用信号的瞬时统 计量作为特征参数，采用多层神经网络作为分类器。计算机仿真表明：当噪声采用高斯白噪声，并且信噪比大于 l5 dB时，识别率高于96％ ；当信噪比不低于l0 dB时，识别率不低于90％。-Existing digital signal automatic modulation recognition methods are mostly applied only to memoryless signals, such as PSK, ASK, FSK signals. Will have a memory signal (MSK signal) and non-memory signal into consideration, an improved digital signal automatic identification method. This method is the use of the instantaneous signal statistics as a characteristic parameter, the use of multi-layer neural network as classifier. Computer simulation shows that: When the noise using Gaussian white noise, and signal to noise ratio greater than l5 dB, the recognition rate is higher than 96 when the signal to noise ratio not less than l0 dB, the recognition rate of not less than 90.
