Chapter 2 discusses the function of optimum array based on the minimum meansquared error principle in CDMA system, the method of produce the reference signal, and proved whether the reference signal is the correspond PN code sequence or respread signal, the result of the array's weight converge can converge the same optimum weight under the condition that the PN sequence in a bit of data is long enough. In this chapter, we finally get the beam pattern and the correlate bit error rate after converge when several CDMA signal arrives in different direction.
