Currently, Visible Light Communication (VLC) technology remains a lagging research in the field of UltraWide Band (UWB), due to the inefficiency of data capture and synchronization period. Accordingly, this paper proposes a fundamental designand implementation of data communication of VLC on the MAC layer based on FPGA. This paper includes basic research context, design and implementation of UWB MAC...
In this paper, we consider a MIMO system with two transmit ports and receiver ports in the power-line communications (PLC), and we propose two space time block codes (STBCs) Finite Feedback Schemes (FFSs) for PLC. In each scheme, the transmitter equips with two STBCs, one corresponding to each of the feedback values, to encode the information bits. Because of the impulsive noise in PLC channels, the...
Aiming at reducing the overhead of codebook design and improving the performance of massive multiple-input multiple-output (MIMO) systems, a novel two-stage codebook design is presented in this paper. Using the householder-transform, which perturbs the first-codebook beam direction, the second-codebook can be easily obtained. In addition, the second-codebook maintains the properties of the first-codebook...
