Hybrid Beamspace DOA Estimation for RF-Chain-Limited mmWave Passive Arrays

Hybrid convolutional beamspace (CBS) is proposed for direction-of-arrival (DOA) estimation based on millimeter-wave (mmWave) passive arrays. In hybrid processing, an analog combiner is used to reduce the number of radio-frequency (RF) chains thereby lowering hardware cost. Then, a digital combiner a...
