Blockwise Phase Rotation-Aided Analog Transmit Beamforming for 5G mmWave Systems
Md. Abdul Latif Sarker, Igbafe Orikumhi, Dong Seog Han +1
In this letter, we propose a blockwise phase rotation-aided analog transmit beamforming (BPR-ATB) scheme to improve the spectral efficiency and the bit-error-rate (BER) performance…

Rate-Loss Mitigation for a Millimeter-Wave Beamspace MIMO Lens Antenna Array System Using a Hybrid Beam-Selection Scheme
Md. Abdul Latif Sarker, Md. Fazlul Kader, Dong Seog Han
The rate loss is an important issue for multi-user beamspace multiple-input multiple-output (MIMO) millimeter-wave systems. In such systems, multi-cluster channel propagation leads…
