Antenna Selection Based on Energy Efficiency of Uplink in Massive MIMO Systems(RF) chain for each antenna. When the number of antennas is small, the power consumption of the RF chains is negligible compared with the transmitting power. However, with the increase of antennas and RF chains, the ratio of the RF chains power consumption to the total transmitting power is graduall

A Multi-local World Network Modelt regions are connected with each other for many reasons, such as work and study. Therefore, on the basis of a local-world evolving network model, we propose and study a network model with the concept of multi-local world connectivity, which simulates Human Daily multi-workspace and multi-residentia

Besides, the utilization of NOMA can greatly increase spectral efficiency and support massive connectivity. So, a cooperative NOMA-based DCO-OFDM VLC system is proposed. All the op

This will cause some secondary users to fail to get the SINR, required for normal communication if the secondary user transmit power is enhanced, although it meets the secondary user communicati
