前后向平滑， music 主要包含经典music算法实现原理及其代码，然后在此基础上介绍了前后向平滑算法的实现及其代码和仿真结果(forward/backward spatial smoothing，MUSIC Consists mainly of classical music algorithm theory and its code, and then on this basis introduced before and after smoothing algorithm and code and simulation results)

一种改进的粒子滤波算法的研究 粒子滤波基本原理，通过改进权重计算、重采样算法， 计算速度得到提高。改进的算法在DSP系统中进行目标跟踪仿真，证明其具有速度快、 精度高的特点(An improved study the basic principles of particle filter particle filter algorithm, recalculation by improving the rights, resampling algorithm to calculate the speed improved. Improved algorithms for object tracking simulation DSP system proved its high speed, high accuracy)

开源的gps matlab程序,包括最小二乘卡尔曼滤波\lambda算法电离层修正\对流层修正星钟修正等 很好的GNSS学习参考(open source of gps, programme in matlab,include LS, ekf, lambda, iono,tron,etc good for gnss study)
