Weighted sumrate maximizing hybrid precoder for MU-MISO-OFDM

In multi-antenna transceivers with all-digital beamforming, the number of radio frequency (RF) chains necessarily equals the number of antennas, which entails a large hardware complexity and power consumption when deploying large antenna arrays. …

Rate-Maximizing Zero-Forcing Hybrid Precoder for MU-MISO-OFDM

Hybrid precoders, consisting of an analog hardware-constrained part operating at radio frequency (RF) and a digital part operating at baseband, reduce the RF implementation complexity and power consumption of multi-antenna transceivers, at the …

A class of reduced-complexity hybrid precoding algorithms for MU-MISO OFDM transmission

In downstream spatial multiplexing involving multicarrier modulation using a hybrid precoder, several trade-offs have to be made with respect to the hardware complexity of the analog part of the precoder, the computational complexity of the …
