MODBUS通信程序.可用于学习施耐得PLC通信、现在国产好多RTU都用MODBUS协议。...

With the advent of multimedia, digital signal processing (DSP) of sound has emerged from the shadow of bandwidth-limited speech processing. Today, the main appli- cations of audio DSP are high quality audio coding and the digital generation and manipulation of music signals. They share common research topics including percep- tual measurement techniques and analysis/synthesis methods. Smaller but nonetheless very important topics are hearing aids using signal processing technology and hardware architectures for digital signal processing of audio. In all these areas the last decade has seen a significant amount of application oriented research.

线性调频信号在宽脉冲内附加线性调频以扩展信号频带，提供了时宽带宽积大于1的信号，有效地解决了大的时宽和带宽不可兼得的矛盾。-LFM pulse width within the additional chirp signal bandwidth expansion, Broadband provides a wide plot when more than one signal, effectively solve the big time and wide bandwidth closest of the contradictions.

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！
