A New MIMO Beamforming Technique Based on Rotation Transformations
Abstract— In this paper, we propose a new transmit beamforming technique for multiple-input-multiple-output (MIMO) systems to improve the link level performance. We present a met...

A New Two-Step Precoding Based on Rotation Transformations in Closed-Loop MIMO Systems
— In this paper, we propose a two-step precoding approach for multiple-input multiple-output (MIMO) systems by dividing the precoding process into two steps: spatial multiplexing...

Adaptive codebook for beamforming in limited feedback MIMO systems
—We propose a new scheme for limited feedback in MIMO systems. We consider transmit beamforming and receiver maximal ratio combining as a base for our work, and propose a novel b...

Blind Estimation of Multiple Carrier Frequency Offsets
Multiple carrier-frequency offsets (CFO) arise in a distributed antenna system, where data are transmitted simultaneously from multiple antennas. In such systems the received sign...
