KalmanFilter_GPS_INS
该程序基于MATLAB平台编写，实现了GPS/INS基于位置松组合的卡拉曼滤波算法，分为两部分，GPS_INS.m为组合算法主文件，输入捷联惯导平台实测数据，设置各量测噪声参数，在调用卡尔曼滤波函数进行数据融合校正，最后实现绘图功能；kalman_GPS_INS.m 为卡拉曼滤波程序，输入量测误差以及各噪声参数可得位置和速度估计值。(The program is based on MATLAB platform, and realizes the Kalman filtering algorithm of GPS/INS based on position loosening combination. It is divided into two parts. GPS_INS.m is the main file of the combined algorithm, inputs the measured data of the strapdown inertial navigation platform, sets the measurement noise parameters, and carries out data fusion correction by calling the Kalman filter function, and finally realizes the drawing. Function; kalman_GPS_INS.m is Kalman filter program, input measurement error and noise parameters can be estimated position and velocity.)

OFDM信号频谱感10
说明：前已提出的频谱感知方法主要包括匹配滤波器检测、能量检测、循环平稳特征检测以及多分辨率频谱感知. 这些方法均为单节点感知方法.然而，在阴影和深度衰落情况下，单个节点的感知结果并不可靠，因此，需要对多个节点的感知结果进行融合，以提高检测可靠性，即协作感知技术. 文献采用“或” 准则对各个 CR 感知结果进行融合. 文献则提出了基于 D-S 证据理论的协作频谱感知算法，虽然该算法的性能比“或” 准则或“与”准则要好，但需要存储大量历史信息，算法的计算复杂度也很高. 文献中分析了采用似然比检测(likelihood ratio test， LRT) 的软判决与采用“与” 准则的硬判决的性能，结果表明采用软判决的协作感知性能更优(Previously proposed spectrum sensing methods mainly include matched filter detection, energy detection, cyclostationary feature detection and multi-resolution spectrum sensing. These methods are all single node sensing methods. However, in the case of shadow and deep fading, the sensing results of single node are not reliable, so, It is necessary to fuse the sensing results of multiple nodes to improve the detection reliability, i.e. cooperative sensing technology. In the literature, "or" criterion is used to fuse the CR sensing results. In the literature, a cooperative spectrum sensing algorithm based on D-S evidence theory is proposed. Although the performance of the algorithm is better than "or" criterion or "and" criterion, a large amount of historical information needs to be stored, The computational complexity of the algorithm is also very high. In the literature, the performance of the soft decision based on the likelihood ratio test)
