Experimental investigation of pointing errors on drone-based FSO systems
(IEEE, 2020-10-05)Airborne free space optical (FSO) links can be efficiently used for backhaul/fronthaul needs of future cellular networks. Unlike terrestrial FSO links where a fixed connection between two buildings is considered, airborne ... -
Experimental investigation of the impact on TCP traffic by hidden video-tagged UDP traffic
(IEEE, 2017)This paper investigates the impact of video-tagged UDP traffic on best-effort TCP traffic in an experimental setup with a novel observation approach. Our setup consists of three 802.11ac nodes in a hidden node topology, ... -
Experimental investigation on the effect of wavelength on aperture averaging in FSO communications
(The Optical Society, 2020-06-01)Atmospheric turbulence is a major impairment in free-space optical (FSO) communication systems. Based on the fact that the size of receiver aperture is much larger than operation wavelength, aperture averaging extracts ... -
Experimental QOS-based comparison of olsr and B.A.T.M.A.N. mesh routing algorithms for multimedia home networks
(2013-08)Wireless Mesh Networks (WMNs) allow communication of two nodes via a multi-hop route, without the need for an infrastructure such as base stations. Routing has been a fundamental issue for this type of communication networks. ... -
An experimental study of a bluetooth communication system for robot motion control
(IEEE, 2019)This paper presents a method that aims to reduce the complex cabling problem in robotics applications, so as to prevent difficulties in troubleshooting processes and failures in case of cable breaks. Examples in the ... -
An experimental study of underwater visible light communication
(IEEE, 2022)Visible light communication (VLC) has emerged as a powerful high-data-rate alternative to conventional underwater acoustic technology for short and medium link distances. In this paper, we develop an experimental underwater ... -
Experimental validation of a novel RLL code for visible light communication
(IEEE, 2020)Flicker arising in visible light communication (VLC) system is typically mitigated by run-length-limited (RLL) codes. The IEEE 802.15.7 standard proposes RLL codes according to the modulation type and data rate. In this ... -
F-Shaped Monopole Antenna
(IEEE, 2017)In this paper, effects of F antenna arm length on the frequency, gain and s11 values are studied. The arms and the total length of the F determine the resonance frequency of the antenna. The inverted F shaped antennas are ... -
Fall detection for elderly people using depth video data obtained by kinect
(2013-08)Automatic detection of unusual events such as falls is very important especially for elderly people living alone. Real-time detection of these events can reduce the health risks associated with a fall. There has been a ... -
Fast and efficient circuit topologies for finding the maximum of n k-bit numbers
(IEEE, 2014-08-01)Finding the value and/or index of the maximum (or minimum) element of a set of n numbers (each with k-bits) is a fundamental arithmetic operation and is needed in many applications. This paper proposes several maximum-finder ... -
Fast incremental least square pose estimation for hardware implementation with rolling shutter camera
(IEEE, 2020-10-05)6 DoF position and orientation estimation is vital for many real-time applications. It is essential to meet low latency, high accuracy and reliability requirements, especially when used for real-time haptic feedback ... -
Fast multiplier generator for FPGAs with LUT based partial product generation and column/row compression
(Elsevier, 2017)We present a new parallel integer multiplier generator for FPGAs. It combines (i) a new Generalized Parallel Counter (GPC) grouping algorithm for column compression with (ii) a LUT based partial product generation, is (iii) ... -
Fast parallel prefix logic circuits for n2n round-robin arbitration
(Elsevier, 2012-08)An n2n round-robin arbiter (RRA) searches its n inputs for a 1, starting from the highest-priority input. It picks the first 1 and outputs its index in one-hot encoding. RRA aims to be fair to its inputs and maintains ... -
Fast two-pick n2n round-robin arbiter circuit
(IEEE, 2012-06)A regular (one-pick) round-robin arbiter circuit picks one active requester (if any) out of n requesters. A two-pick round-robin arbiter selects up to two requesters. An n2n two-pick round-robin arbiter indicates the picked ... -
Fast, secure, and remote multiboot of FPGAs
(2012-09)The purpose of this thesis is to develop an efficient framework to implement secure FPGA-based (Field Programmable Gate Array) systems. An FPGA is a reconfigurable device that has the ability to adapt the hardware during ... -
Fast-decodable MIMO HARQ systems
(IEEE, 2015-05)This paper presents a comprehensive study on the problem of decoding complexity in a Multi-Input Multi-Output (MIMO) Hybrid Automatic Repeat reQuest (HARQ) system based on Space-Time Block Codes (STBCs). We show that there ... -
Feedback-free adaptive modulation selection algorithm for FSO systems
(IEEE, 2021-09)Free space optical (FSO) communication systems experience turbulence-induced fading. As a possible solution to mitigate the effects of fading, adaptive transmission that allows the adjustment of transmission parameters ... -
Finite-SNR diversity gain analysis of FSO systems over gamma-gamma fading channels with pointing errors
(IEEE, 2021-06)Free space optical (FSO) communication systems are subject to turbulence-induced fading as a result of fluctuations in the refractive index. Gamma-Gamma (GG) distribution is commonly used in the literature to characterize ... -
Finite-SNR diversity-multiplexing tradeoff for network coded cooperative OFDMA systems
(IEEE, 2017-03)Network-coded cooperation (NCC) is an effective method to improve the throughput efficiency in cooperative wireless networks. The combined use of orthogonal frequency division multiplexing (OFDM) with NCC has been further ... -
