A MIMO algorithm for smart antenna in CDMA systems

We propose a simple and efficient adaptive blind-beamforming algorithm for CDMA systems. The algorithm requires no reference signal. Since the algorithm uses a sequential method to compute a complex matrix, its computational complexity is very low without any degradation of its performance. A MIMO model is also proposed for the algorithm. Computer simulations, considering the Rayleigh fading channel in a CDMA environment, are presented to verify the performance.
