自适应平方根中心差分卡尔曼滤波算法在捷联惯性导航系统大方位失准角初始对准中的应用
一种自适应平方根中心差分卡尔曼滤波算法（ASRCDKF），并应用于捷联惯性导航系统（SINS）大方位失准角初始对准中。ASRCDKF 算法以中心差分变换为基础，基于平方根滤波能够克服发散的思想，利用协方差平方根代替协方差参加递推运算，并将自适应估计原理引入该算法中，不仅克服了扩展卡尔曼滤波产生线性化误差和计算雅可比矩阵的不足，而且减小了计算量，保证了数值稳定性。同时，ASRCDKF 算法解决了传统滤波算法过度依赖系统动态模型和噪声统计特性先验知识的问题。通过滤波仿真，进一步表明了ASRCDKF 算法在SINS 大方位失准角初始对准中的有效性和优越性。

LTE专题研究之物理层OFDM/SC-FDMA原理
正交频分复用(OFDM: Orthogonal Frequency Division Multiplexing)是一种多载波调制技术，早在20世纪60年代就已经提出了OFDM的概念，不过由于实现复杂度高，大家并不怎么关注，之后随着DFT(离散傅立叶变化)、FFT(快速傅立叶变换)的提出以及DSP芯片技术的发展，极大减少了OFDM实现复杂度和成本，OFDM逐步在通信领域得到了广泛的应用，并且成为了高速移动通信中的主流技术。OFDM使用相互重叠但正交的窄带传输数据，相比传统的多载波系统具有更高的频谱利用率。3gpp选择OFDM作为LTE下行数据传输制式。由于OFDM信号是多个子载波信号的叠加，所
