| Abstract: | In this paper,the basic principle of p code generator is introduced,and then it produces P code using matlab.Furthermore,it analyzes its characteristic of autocorrelation and cross-correlation,which provides the proof for further study directing P code acquisition and decipher of P(Y) code.The results of simulation prove that the programme which produces P code is preciseness. |
