| Abstract: | Pseudo-random code will be widely applied in many field because of its anti--jamming capability, so how to encode and jam this signal is very necessary to study. Firstly, mechanism and characteristics of Pseudo--random code＇s generation are given in this paper. Then the way of bit width acquisition and period detection is introduced using its characteristics of balance, run distribution and auto--correlation. Finally, the influence on jamming effect caused by error bit and delay error is studied and the reasons causing above influencing factors are analyzed and corresponding reducing solutions are given. |
