A simple angle of arrival estimation system
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
We propose a practical, simple and hardware friendly, yet novel and very efficient, angle of arrival (AoA) estimation system. Our intuitive, two-phases cross-correlation based system requires a switched beam antenna array ...
The effect of transmitter's eavesdropper CSI on the secure degrees of freedom of the MIMO MAC
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
We investigate the secure degrees of freedom (SDoF) of the two-transmitter multiple access channel (MAC) with multiple antennas transmitters and multiple antennas legitimate receiver in the vicinity of an eavesdropper that ...
On the secure degrees of freedom of the K user MIMO MAC with statistical CSI
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
We investigate the secure degrees of freedom (SDoF) of the K-user MIMO multiple access channel (MAC) in the vicinity of an eavesdropper which is trying to decode the messages sent by the transmitters. The eavesdropper is ...
Self-interference cancellation using time-domain phase noise estimation in OFDM full-duplex systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
In full-duplex systems, the local oscillator phase noise (PN) problem is one of the bottleneck challenges that may face the self-interference cancellation (SIC) stage especially when orthogonal frequency division multiplexing ...
Optimal power allocation in dispersed cognitive radio systems with carrier aggregation
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this paper, we investigate the optimal power allocation problem in dispersed cognitive radios with carrier aggregation. To this end, we model the carrier aggregation using an i - th frequency diversity policy, wherein ...
Performance of non-coherent decode-and-forward relaying over time-varying fading channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Performance analysis of selection combining (SC) for decode-and-forward (DF) relaying in case of general time-varying Rayleigh fading channels is investigated. While auto-regressive (AR) time series model is applied in ...
Impact of stochastic RF energy harvesting relay on wireless point-to-point network
(
Institute of Electrical and Electronics Engineers Inc.

In this paper, we study a general practical stochastic energy harvesting (EH) model where in, an EH relay is able to harvest energy from the radio frequency (RF) radiation in a super capacitor. The different aspects of ...
Capacious spread spectrum watermarking utilizing hadamard matrix
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this paper, a new watermarking method based on spread spectrum technique, which we call capacious spread spectrum (CSS) is proposed. In this method, unlike the traditional spread spectrum watermarking (TSS), more than ...
Optimized collaborative spectrum sensing in energy harvesting cognitive radio networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
We study the probability of error optimization problem in collaborative spectrum sensing (CSS) with limited time and energy resources in energy harvesting cognitive radio (CR) networks. The frame structures for sensing and ...
On the performance of spectrum sensing based on GLR for full-duplex cognitive radio networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In cognitive radio networks, secondary users (SUs) utilize the unused spectrum slots in the assigned band for the primary users (PUs). Conventional cognitive radio networks operate in half-duplex (HD) mode. Recently, ...
