基于MATLAB写的调试通过的QRS检测算法，具有信噪比估计、阀值预测的斜率检测算法。(Written based on MATLAB debugging through the QRS detection algorithm, with SNR estimation, prediction of the slope threshold detection algorithm.)

说明：  一个多目标跟踪的matlab代码,里面附有说明文档.其中背景差分法可以实现实时更新.该代码在检测与跟踪少量目标时效果很好,但是跟踪目标大于8后,效果下降很多(A multi-target tracking matlab code, which accompanied by documentation. Including real-time background subtraction method can be updated. The code in small target detection and tracking works well, but the tracking target is greater than 8, the effect of decreased number of)

说明：  一种未知信源数的高分辨DOA 估计算法：众多性能优良的超分辨波达方向(DOA)估计算法通常需要预先判定信源数目，然而，现有的信源数估计 算法在有限采样快拍条件下，估计性能随着信噪比的降低而下降，错误概率也相应增加，最终导致DOA 估计失败。 该文提出一种超分辨的DOA 估计算法，此算法不需要预判信源个数和进行特征值分解，同时在时变环境中，针对 快拍数较少的情况下，依然保持较高的角度分辨能力，可以被认为是综合了Capon 法和MUSIC 法的优点。(Algorithm on High Resolution DOA Estimation without Sources Number：Many of the super resolution DOA(Direction-Of-Arrival) estimation algorithms presume the number of signal sources. Since the sample snapshot is limited, however, the available algorithms on source number estimation may fail at lower SNR. In this paper, a novel algorithm for high resolution DOA estimation is proposed, which not only skips sources number estimation and EVD, but also behaves satisfactorily with a few snapshot, it may be viewed as a combination of merit of conventional Capon and MUSIC method.)

算法能实现数据的自动生成，有瑞士面包卷、双峰数据等(The algorithm can automatically generate the data, the Swiss rolls, doublet data,)

说明：  MATLAB仿真的QPSK系统，包括非常详细的系统结构图，系统分析，仿真分析，代码等等(MATLAB simulation of the QPSK system, including a very detailed system architecture diagram, system analysis, simulation analysis, code, etc.)
