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.)

this is background subtraction code.

本人亲手做的一个matlab扩频通信系统simulink仿真系统。从发送端到接收到，每部分都相应得加了示波器或频谱仪，可以对照理论清楚观察到信号发生的变化。matlab6.5及以上版本上运行。(I personally make a matlab Spread Spectrum Communication System simulink simulation system. Send-ended to receive from every part of a corresponding increase in the oscilloscope or spectrum analyzer can be clearly observed in the control theory of signal changes. matlab6.5 and above to run.)

利用stft实现了跳频信号的跳周期估计 简单的进行了跳频信号的仿真，然后利用短时傅里叶变换对跳频信号进行分析，再对得到的时频矩阵提取时间平面，对时间序列去直流，进行傅里叶变换，最后实现得到跳周期。(estimates the hopping time of the sfh by stft )
