MIMO Wiretap Channels: Secure Transmission Using Transmit Antenna Selection and Receive Generalized Selection Combining

Optimal Transmit Antenna Selection for Massive MIMO Wiretap Channels

In this paper, we study the impacts of transmit antenna selection on the secrecy performance of massive MIMO systems. We consider a wiretap setting in which a fixed number of transmit antennas are selected and then confidential messages are transmitted over them to a multi-antenna legitimate receiver while being overheard by a multi-antenna eavesdropper. For this setup, we derive an accurate ap...

Receive Soft Antenna Selection for Noise-Limited/Interference MIMO Channels

Although the Multi-Input and Multi-Output (MIMO) communication systems provide very high data rates with low error probabilities, these advantages are obtained at the expense of having high signal processing tasks and the hardware cost, e.g. expensive Analog-to-Digital (A/D) converters. The increased hardware cost is mainly due to having multiple Radio Frequency (RF) chains (one for each antenn...

Performance of Spatial Multiplexing and Transmit Diversity in Multi-Polarized MIMO Transmissions with Receive Antenna Selection

In this work, we consider the use of multiple antenna signaling technologies, specifically space-time block coding (STBC) and spatial multiplexing (SM) schemes, in multiple-input multiple-output (MIMO) communication systems employing dual polarized antennas at both ends. The use of dual-polarized antennas theoretically double the number of virtual antennas used in the system. On the other hand,...

Iterative Transmit/Receive Antenna Selection in MIMO Systems Based on Channel Capacity Analysis

Transmit/receive Antenna Selection for Mimo Systems to Improve Error Performance of Linear Receivers

Recent work has shown that multiple antenna transceivers can be used to enhance the data-rates and coverage of wireless links as compared to single antenna transceivers. However, using multiple antennas requires costly hardware and is computationally intensive. Antenna selection could be done at the transmitter and/or the receiver to overcome these disadvantages while incurring minimal loss in ...
