Abstract :
We propose two blind LMS and MMSE algorithms for adaptive array antennas. The algorithms require neither spatial knowledge nor reference signals. Both of the algorithms are the combination of the finite symbol property of the digital signal and the conventional LMS and MMSE algorithms. Computer simulations were carried out with and without taking the multipath Rayleigh fading effect into account in the CDMA environment so that the performance of the algorithms can be investigated
