说明: 用MATLAB在产生的观测数据中捕获其中PRN 号码为“5”C/A 码。
(1) 观测数据应该有一定的多普勒频偏D f(-10kHz〈D f〈+10kHz);
(2) 加入高斯白噪声,使其信噪比为-20dB;
(3) 捕获成功后,应给出捕获标志,并给出估计的频偏和码偏值。
(Generated by MATLAB in which observed data capture PRN number is " 5" C/A code. (1) there should be some observations of Doppler shift D f (-10kHz < D f < +10 kHz) (2) by adding Gaussian white noise, so SNR is-20dB (3) capture success After the capture flag to be given, and given the estimated frequency offset and code bias values.)
