Beam Selection-Based Hybrid Precoding
2021 IEEE 93rd Vehicular Technology Conference (VTC2021-Spring), 2021 The deployment of large antenna arrays at the base station is a prerequisite for operating at the millimeter wave bands. The large antenna arrays are required to achieve high beamforming gains and thus to guarantee sufficient received signal power.

Interference Exploitation-Based Hybrid Precoding With Robustness Against Phase Errors [PDF]
IEEE Transactions on Wireless Communications, 2019 Hybrid analog-digital precoding significantly reduces the hardware costs in massive multiple-input multiple-output (MIMO) transceivers when compared with fully digital precoding at the expense of increased transmit power.

Full-Duplex mmWave Communication with Hybrid Precoding and Combining
2020 28th European Signal Processing Conference (EUSIPCO), 2021We investigate the design of hybrid precoders and combiners for a millimeter wave (mmWave) point-to-point bidirectional link in which both nodes transmit and receive simultaneously and on the same carrier frequency. In such full-duplex configuration, mitigation of self-interference (SI) becomes critical.

Hybrid Precoding for HAP Massive MIMO Systems
2020A hybrid precoding scheme is proposed for high altitude platform (HAP) massive multiple-input multiple-output (MIMO) systems to obtain the radio frequency (RF) precoder and the baseband precoder with limited RF chains. We first exploit duality theory to derive the relation between the statistical channel state information (SCSI) and RF precoder, which ...

Wideband hybrid precoder for massive MIMO systems
2015 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2015This paper studies wideband hybrid precoder for downlink space-division multiple-access and orthogonal frequency-division multiple-access (SDMA-OFDMA) massive multi-input multi-output (MIMO) systems. We first derive an iterative algorithm to alternatingly optimize the phase-shifter based wideband analog precoder and low-dimensional digital precoders ...
