PROJECT TITLE :

Downlink Beamforming for Energy-Efficient Heterogeneous Networks With Massive MIMO and Small Cells - 2018

ABSTRACT:

A heterogeneous network (HetNet) of a macrocell base station equipped with a giant-scale massive multi-in multi-out (MIMO) antenna array overlaying a range of little cell base stations (tiny cells) can provide top quality of service (QoS) to multiple users under low transmit power budget. But, the circuit power for operating such a network, that is proportional to the number of transmit antennas, poses a drawback in terms of its energy potency (EE). This Project addresses the beamforming design at the base stations to optimize the network EE under the QoS constraints and a transmit power budget. Beamforming tailored for weak, robust, and medium cross-tier interference HetNets is proposed. In distinction to the standard transmit strategy for power potency in meeting the users' QoS necessities, that counsel the utilization of some hundred antennas, it's revealed that the overall network EE quickly drops if this variety exceeds 50. It's found that, for a given number of antennas, HetNet is more energy efficient than large MIMO when considering the energy consumption.
