Energy Efficiency in Massive MIMO-Based 5G Networks: Opportunities and Challenges
K. N. R. Surya Vara Prasad, Ekram Hossain, Vijay K. Bhargava
As we make progress towards the era of fifth generation (5G) communication networks, energy efficiency (EE) becomes an important design criterion because it guarantees sustainable…
Per-Antenna Constant Envelope Precoding for Secure Transmission in Large-Scale MISO Systems
Jun Zhu, Ning Wang, Vijay K. Bhargava
Secure transmission in large-scale MISO systems employing artificial noise (AN) is studied under the per-antenna constant envelope (CE) constraint. Achievable secrecy rate of the p…
Linear Precoding of Data and Artificial Noise in Secure Massive MIMO Systems
Jun Zhu, Robert Schober, Vijay K. Bhargava
In this paper, we consider secure downlink transmission in a multi-cell massive multiple-input multiple-output (MIMO) system where the numbers of base station (BS) antennas, mobile…
