摘　　要：For direct sequence spread spectrum (DSSS) communication systems suffering interference, it is known that code-aided interference suppression technique outperforms all of the previous linear or nonlinear methods. In this paper, we proposed an improved code-aided technique which can improve the system performance greatly by using the eigenvector sign (EVS) spreading sequence which depends on the statistical characteristics of the interference and the thermal noise.For direct sequence spread spectrum （DSSS） communication systems suffering interference, it is known that code-aided interference suppression technique outperforms all of the previous linear or nonlinear methods.
