- Abstract
In Code Division Multiple Access(CDMA) multi-UAV TT&C spread spectrum link, Multiple Access Interference(MAI) is an important factor to be considered in multi-target system in which the first task is to design spread spectrum code with cross correlation according to the anti-MAI requirement. Starting with the requirement of UAV for anti-MAI capability, this paper analyzes the effect of such factor as spread spectrum rate, number of users, and cross correlation on anti-MAI performance, draws the conclusion that the Kasami code has good cross correlation and the sequence partial correlation can reduce the cross correlation performance. Simulation result verifies the theoretical analysis.
