quick-acquisitionmethod-of-signals
主要研究了两种高动态扩频信号快速捕获的方法,即基于FFT 的频域(载波) 并行捕获法和基于FFT 的时域(伪码)
并行捕获法,并使用MATLAB 进行了仿真和比较。仿真结果表明:基于FFT 的频域并行捕获可捕获较大的频偏并跟踪一定
的频率变化率,可用于卫星变轨等高动态、高加速度等飞行过程。而基于FFT 的时域并行捕获可快速捕获码相位,用于在轨飞行的飞行器,可根据轨道参数提前预报其多普勒频偏,但同时需要精密测距的飞行过程。(Research on the quick acquisition method of the high dynamic spread spectrum signals)

OFDM_Channel-estimation
OFDM(正交频率调制)实现多载波调制基本思想是将带宽信道分解成许多并行的窄子信道,是每个子信道的想干带宽,从而实现平稳衰落。搭建了完整的OFDM信道链路系统,运用三种不同的信道估计方法(LS信道估计、DFT信道估计、Improved-DFT信道估计),并对AWGN理想信道和衰落信道误码情况进行了仿真和比较。(OFDM (Orthogonal Frequency Modulation) multicarrier modulation basic idea bandwidth channel is decomposed into a number of parallel narrow subchannels, each subchannel wanted bandwidth, in order to achieve a smooth fading. Build a complete OFDM channel link system, the use of three kinds of different channel estimated method (LS channel estimated, to the DFT letter Tao estimates, Improved-the DFT letter Road estimated), and AWGN ideal letter Road and fading channel bit error situation conducted a simulation and comparison .)

SPEI
说明: 标准化降水蒸散发指数 matlab的代码(Standardized index precipitation evaporation for matlab),直接按照例子中的数据格式运行SPEI_Cal.m文件,运行结果在stacking中查询,可以自己修改时间尺度,亲测可用。(The program calculates a time series of the Standardised Precipitation-
Evapotransporation Index (SPEI) at a given time interval from an input data file
containing monthly time series of precipitation and mean temperature, plus the
geographic coordinates of the observatory.)
