设计一维纳滤波器 (1)产生三组观测数据：首先根据s(n)=a s(n-1)+w(n)产生信号s(n)，将其加噪（信噪比分别为20dB,10 dB，6 dB），得到观测数据x1(n), x2(n), x31(n). (2)估计xi(n)，i=1,2,3的AR模型参数。假设信号长度为L，AR模型阶数为N，分析实验结果，并讨论改变L,N对实验结果的影响。 (A Wiener filter design (1) to produce three sets of observations: first generating a signal s (n) according to s (n) = as (n-1)+w (n), to add noise (20dB SNR, respectively , 10 dB, 6 dB), to obtain observational data x1 (n), x2 (n), x31 (n). (2) estimate xi (n), i = AR model parameters 1,2,3. Assuming the signal length L, AR model of order N, analysis of experimental results and discuss the impact changing L, N of the experimental results.)

用Matlab处理GPS导航卫星观测数据的程序，也就是O文件，Rinex 2.11版本，代码仅200多行，且包含大量注释，于2017.12.2日调试通过，可顺利读取体积达10M+的O文件，读取的数据准确无误。函数调用格式： [APXYZ DeltaHEN signal_type obsdata] = read_obs(‘krgg3340.17o’)(Using Matlab to process GPS navigation satellite observation data program, that is, O file, Rinex 2.11 version, the code is only more than 200 rows, and contains a lot of annotations. It debugged on 2017.12.2 day. It can smoothly read the O file with volume up to 10M+, and the data read is accurate.)
