Adaptive digital beamforming in cellular CDMA systems using noniterative signal subspace tracking

We introduce a novel adaptive digital beamforming algorithm for application in cellular CDMA communications systems. A noniterative rank-one signal subspace eigenstructure update (NR1SSU) algorithm enables low-complexity recursive processing of beamforming weights. A PN chip-level IS-95 CDMA referen...

Summary:We introduce a novel adaptive digital beamforming algorithm for application in cellular CDMA communications systems. A noniterative rank-one signal subspace eigenstructure update (NR1SSU) algorithm enables low-complexity recursive processing of beamforming weights. A PN chip-level IS-95 CDMA reference model has been used to test the beamforming algorithm via simulation. Our results show that accurate beamforming can be achieved to moving mobiles at one update per IS-95 frame of 192 data bits.
