LTE仿真代码

主要 对无线定位TDOA CHAN算法以及TAYLOR算法进行误码仿真并且仿真了一种两算法相结合的算法 并对误码进行比较(The content is mainly to simulate Chan Algorithm and Taylor Algorithm ,then compare their error performance.Based on them,A new Algorithm combining the two type of Algorithm is also proposed.)

dac8568驱动程序编程，可以控制dac8568进行输出(Dac8568 driver programming)

基于Matlab的OFDM原理仿真，调制解调的原理仿真，通过输出的星座图进行分析(Simulation based on Matlab OFDM principle, the principle of modulation and demodulation simulation output constellation diagram analysis)

捷联惯性导航与GPS组合导航。采用matlab实现。采用自适应算法对其进行处理。并取得了很好的效果。(Strapdown inertial navigation and GPS Navigation. Using matlab to achieve. Adaptive algorithm used to deal with them. And has achieved good results.)

说明：  4. 试说明卷积编解码的工作原理： (1) 使用Simulink仿真卷积编码，并用Viterbi译码的方法进行解码，其中的编码、译码全部是自己编写代码(S-Function方式)，不是调用Simulink的已有编码、译码函数。 (2) 请在加性白高斯噪声信道中，画出比特信噪比与误码率的关系曲线。(4. Try to explain the working principle of convolutional codec: (1) Simulink was used to simulate convolutional coding, and Viterbi decoding method was used for decoding. The coding and decoding were all written by oneself (s-function method), rather than calling the existing coding and decoding functions of Simulink. (2) in the additive white gaussian noise channel, please draw the curve of the relationship between bit signal-to-noise ratio and bit error rate.)

说明：  Astar航迹规划，针对二维飞行航迹进行路径规划，动态规划过程(Astar route planning)

EMW模块说明书 wifi模块 说得很详细(EMW module manual the EMW module manual EMW module manual EMW module manual)

使用周期图法进行谱估计，主要使用自相关算法和直接法(We use the periodogram method to estimate the spectrum, mainly using autocorrelation algorithm and direct method.)

Offset between filter input samples (see notes).

说明：  空域零陷，首先用doa技术估计直达波方向，然后置零，用于直达波消除。(In spatial nulling, DOA technique is used to estimate the direction of direct wave, and then zeroing is used to eliminate direct wave.)
