摘要：
A blind adaptive decorrelating detector is proposed which consists of two vectors: one is the pre-assigned spreading code of the desired user and the other is orthogonal to it. The orthogonal vector is adjusted adaptively to minimise the multiple access interference (MAI). This blind adaptive detector requires no more knowledge than does the conventional single-user receiver. Simulation results show that the obtained performance is close to that of the decorrelator.
