A novel multitarget adaptive array algorithm for wireless CDMA systems using block affine projection

This paper presents a novel blind adaptive array algorithm for CDMA systems employing the despread-respread technique in conjunction with the block affine projection algorithm. The block affine projection despread respread multitarget array (AP-DRMTA) algorithm is developed and compared with the least squares despread respread multitarget array (LS-DRMTA) algorithm, the least squares despread respread multitarget constant modulus algorithm (LS-DRMTCMA) and the block RLS-despread respread multitarget array (block RLS-DRMTA). Computer simulation in both the AWGN static channel and the dynamic channel is performed. The simulation results indicate that the AP-DRMTA has superior bit error rate performance.
