Adaptive AoA Estimation and Beamforming with Hybrid Antenna Arrays [PDF]
2009 IEEE 70th Vehicular Technology Conference Fall, 2009 A new type of hybrid antenna array consisting of analogue subarrays followed by a digital beamformer is proposed for practical implementation of long range high data rate millimetre wave communications systems. An adaptive algorithm, referred to as the differential beam search (DBS), is proposed for the angle of arrival (AoA) estimation to control the ...
