Detaily, the essay analyses signal format of signal of PCH and RACH to get their specific meanings of each field respectively. Then, edit channel codes, modulate GMSK and emulate by MATLAB to get their I & Q time domain waveform.
具体地说本文详细分析了寻呼信令和随机接入信令的信令格式,并且根据其格式编写了虚假的寻呼信令和虚假的随机接入信令,通过信道编码和GMSK调制,最后利用MATLAB仿真,得到他们的I、Q两路时域波形,并且给出了利用虚假信令进行干扰的三种方法。
