Abstract

For direct sequence spread spectrum communication systems suffering interference, 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 further improve the system performance greatly by using the eigenvector sign spreading sequence proposed in this paper, which depends on the statistical characteristics of the interference and the thermal noise.
