Secrecy Rate of Cooperative MIMO in Presence of a Location Constrained Eavesdropper
Zhong Zheng, Zygmunt Haas, Mario Kieburg
We propose and study the cooperative MIMO architecture to enable and to improve the secrecy transmissions between clusters of mobile devices in the presence of an eavesdropper with…
Ergodic Fading MIMO Dirty Paper and Broadcast Channels: Capacity Bounds and Lattice Strategies
Ahmed Hindy, Aria Nosratinia
A multiple-input multiple-output (MIMO) version of the dirty paper channel is studied, where the channel input and the dirt experience the same fading process and the fading channe…
Hybrid Spatio-Temporal Artificial Noise Design for Secure MIMOME-OFDM Systems
Ahmed El Shafie, Zhiguo Ding, Naofal Al-Dhahir
This paper investigates artificial noise injection into the temporal and spatial dimensions of a legitimate wireless communication system to secure its transmissions from potential…
Achievable Rates of Buffer-Aided Full-Duplex Gaussian Relay Channels
Ahmed El Shafie, Ahmed Sultan, Ioannis Krikidis +2
We derive closed-form expressions for the achievable rates of a buffer-aided full-duplex (FD) multiple-input multiple-output (MIMO) Gaussian relay channel. The FD relay still suffe…
Lattice Coding and Decoding for Multiple-Antenna Ergodic Fading Channels
Ahmed Hindy, Aria Nosratinia
For ergodic fading, a lattice coding and decoding strategy is proposed and its performance is analyzed for the single-input single-output (SISO) and multiple-input multiple-output…
Design and Analysis of Sparsifying Dictionaries for FIR MIMO Equalizers
Abubakr O. Al-Abbasi, Ridha Hamila, Waheed U. Bajwa +1
In this paper, we propose a general framework that transforms the problems of designing sparse finite-impulseresponse linear equalizers and non-linear decision-feedback equalizers,…
