In this paper, we propose a novel blind adaptive multiuser detector using the recursive least squares (RLS) algorithm based on singular value decomposition (SVD) for code division multiple access systems. The new presented algorithm can overcome the disadvantages of numerical instability and divergence of the conventional RLS algorithm. Simulation results show that the novel SVD-based RLS algorithm is superior to the conventional RLS algorithm in convergence rate, numerical stability and robustness.
