Block based RLS de-spread re-spread multitarget array: algorithm and performance

We develop a new blind adaptive array algorithm for a CDMA system by using de-spread re-spread directing and variable step size steepest gradient method. It tries to exploit all the received data and still saves the computation load for about two thirds compared to LS-DRMTA.. Its performance is compared with that of LS-DRMTA and LS-DRMTCMA.. Simulation results show that block RLS-DRMTA outperforms them in all the test situations.
