An algorithm to detect and recognize interferences embedded in a direct sequence spread spectrum (DSSS) communication system is proposed. Based on Welch's a
The nonlinear dynamic system of spacecraft with uncertainty and coupling is analyzed and its general dynamical equation is given.The decoupling-ability and cont
超分辨率图像复原是病态反问题.采用Geman & McClure范数来构造数据拟合项,并且在经典的双边全变分(Bilateral total variation,BTV)正则化模型基础上,提出了一种能更有效利用方向信息的正则化模型,该模型根据迭代次数来自适应选择正则化参数.实验表明,该方法比采用L1范数和L2范数能更好地抑制噪声和保持边缘,在视觉效果和峰值信噪比(Peak signal noise
