Abstract :
An alternative blind adaptive algorithm is proposed for CDMA antenna arrays. It requires neither decision feedback nor post-correlation matrix estimation. Simulations show that it outperforms the despread-respread approach with similar complexity and approaches the performance of the code filtering approach with less complexity.
