Downlink Performance of Pilot-Reused HetNet With Large-Scale Antenna Arrays

User and Antenna Joint Selection in Multi-User Large-Scale MIMO Downlink Networks

Performance evaluation of first Iranian large scale photovoltaic power plant

In recent years, due to the fact that non-renewable energies come to an end, renewable energy is expected to provide a significant part of the future needs of Iran. Among these energies, solar energy is a suitable option for a wide range of the country, due to availability, proper radiation intensity, and high sunshine times during the year (about 300 sunny days per year). The purpose of this p...

Performance of Smart Antenna Arrays with Maximal-ratio Eigen-combining

Conventionally, maximum average signal-to-noise ratio beamforming (Max-ASNR BF) and maximal-ratio combining (MRC) are applied to antenna array systems. A recently-proposed combining approach based on the Karhunen-Loève Transform (KLT) followed by MRC of the strongest resultant signals, denoted herein as maximal-ratio eigen-beamforming (MREC), was claimed to be superior and flexible compared to ...

Scheduling in Large Scale MIMO Downlink Systems

This dissertation deals with the problem of scheduling in wireless MIMO (MultipleInput Multiple-Output) downlink systems. The focus is on the large-scale systems when the number of subscribers is large. In part one, the problem of user selection in MIMO Broadcast channel is studied. An efficient user selection algorithm is proposed and is shown to achieve the sum-rate capacity of the system asy...

CDMA Downlink Transmission with Transmit Antenna Arrays and Power Control in Multipath Fading Channels

Wireless code-division multiple-access (CDMA) cellular downlink communications with transmit antenna arrays in multipath fading channels is studied. Various array signal processing techniques at the transmit end are investigated and compared under various settings, in conjunction with power control. No instant downlink channel information is assumed; however, the obtained results are also compa...
