A daptive Algorithm Based on Pilot-Channel for MMSE MULTIUSER Detection in Downlink CDMA*
IEICE TRANS. FUNDAMENTALS: VOL.E83-A. NO.11 NOVEMBER 2000,-0001,():
A novel adaptive algorithin based on pilot chan-nel (PCA) for MMSE muliuser detcction in downlink CDMA is proposed in this paper. This algorithm ases the information in pilot channel to compute the desired weight vector dieetly. Compared with conventional adaptive algorithms [7] and blind algorithms, it does not require training sequences nor chaunel estimation. Analysis shows that the weight vector obteined by the PCA algorithm converges to the Wiener solution globally and its computational complexity is O (N2). Simulation results show that the. PCA algorithm can adapt rapidly to the changing en-vironment. The steady state performance can be enhanced by increasing sthe transmitted power in pilot channel, but is worse than that of conventional reeursive least-square (RLS) algorithm in decision-directed mode. A tso, performance of the adaptive MMSE detcctor is much better than that of conventional RAKE receiver
