is more serious in VAD. That is, the interference from K is more important than N.

IV. CONCLUSION

From simulation results, we find that it is indeed a feasible way to achieve the purpose of multiplexing different prime codes system to commonly share a transmission channel. We Ž . use two ways VAM and PAM to insert P -codes into 3 P -codes. These two ways are the fixed slot method and easily 7 controlling the inserting P -code. On the other hand, the 3 fixed position method for inserting P -code cannot provide 3 Ž . the best control for various combinations of P -code 823543 .

The simulation results have shown that the main interference in the different prime code systems is PAM. Consider adding to P -code the number 3; the system using PAM fails, 3 and the system using VAM still has 1847 successful numbers. Therefore, we can conclude that VAM is a better design algorithm than PAM.
