Millimeter waves is considered to be one of the solutions that will be used in the next generation communications to meet the increasing data demands due to the wide bandwidth provided. However, using these bands in the outdoors environment requires high directivity between the transmitter and the receiver to overcome the severe propagation losses. This paper presents the spectral efficiency analysis...
In this paper, time-domain characteristics of human body channel communication (BCC) are measured with an analog frontend (AFE) printed circuit board (PCB) at different transmission distances and signal frequencies. In addition, a 1 Mb/s to 40 Mb/s wideband signaling (WBS) BCC transceiver which uses the human body skin as a transmission medium is presented. As compared to wireless transmission methods,...
Current mm-wave indoor propagation analysis techniques have limited options when it comes to more than one transmitter and receiver. Experimental testbed hardware is expensive and state-of-the-art simulation methods, such as statistical channel models, are limited to specific scenarios. To overcome these problems, we present mmTrace, a fast deterministic image-based ray-tracing simulation framework...
This work is devoted to the design of an analog transceiver for the Aeronautical Radio Navigation Services band (960 to 1215 MHz) as a required step to the exploitation of the Software Defined Radio concept in avionics. The integration of all the equipment operating in this band into a single piece of reprogrammable hardware minimizes the size, weight, power and cost (the so-called SWaP-C requirements)...
The vision of multi Gbit/s data rates in future mobile networks requires the change to millimeter wave (mm-Wave) frequencies for increasing bandwidth. As a consequence, new technologies have to be deployed to tackle the drawbacks of higher frequency bands, e.g. increased path loss. Development and verification of those novel technologies required an understanding of the propagation effects at mm-Wave...
More and more frequency bands as well as receiver ports are integrated in a single silicon device. This is caused by the rapid development of cellular technologies towards highly integrated multimode transceivers capable of worldwide interoperability in multiple frequency bands. For ensuring highest quality standards in customer delivery, accurate testing and characterization of all these ports is...
This paper describes a low power communication architecture for 2U class nano-satellites. The system is designed to operate two links in the UHF and VHF bands, each of which is managed by independent microcontrollers. Impedance matching networks and harmonic filters are designed to ensure that the maximum power is transferred and spurious emissions are within the acceptable limits. It contains a transceiver...
This work describes a 1 Gb/s digital communication system implemented on an FPGA-based platform to investigate mixed-signal calibration techniques of time-interleaved analog-to-digital converters (TI-ADCs). Design of multi-gigabit TI-ADCs is of great interest for next generation digital communication systems such as optical coherent networks. In these applications, mismatches of the sampling time,...
It is expected that by the year 2020, a new mobile telecommunication standard will have rolled out that would allow more flexibility compared to today's systems. While the waveform for 5G is still a topic of much debate, three major contenders have been presented: OFDM, FBMC, and UFMC. In this paper, we will look over these waveforms and their proposed transceivers before going into the types of filters...
In this paper, we propose the principle of construction wideband high data rate wireless communication system based on multiple low rate IEEE 802.11n modems (up to 150 Mbps each) with transferring the group signal into THz band. Proposed approach allows to build high speed (1.2 Gbps and more) wireless transport networks for distances around 1 km. We developed two laboratory transceivers accordingly...
We provide a discussion of the Controller Area Network (CAN) networking protocol as used in space applications and then report the results of destructive and nondestructive single-event effects (SEE) testing of the Intersil ISL72027SEH CAN bus transceiver. We conclude with a brief discussion of 60Co total ionizing dose (TID) testing results.
This forum covers the greatest calibration and dynamic matching techniques for data converters, showing the way these have changed modern transceivers and applications.
The Internet of Everything (IoE) is a macro trend that is presently disrupting the global electronic industry. Tremendous growth is forecast in the areas of sensing, measurement and the interpretation of data, before transferring to the Cloud for analysis. This exponential increase in wireless-sensor traffic, coupled with increasingly harsh environments in which sensor networks operate around the...
With the rapid growth of data traffic in data centers, data rates over 50Gb/s/signal (e.g., OIF-CEI-56G-VSR) will eventually be required in wireline chip-to-module or chip-to-chip communications [1–3]. To achieve better power efficiency than that of existing 25Gb/s/signal designs, a high-speed yet energy-efficient front-end is needed in both the transmitter and receiver. A receiver front-end with...
This paper proposes an active RFID-based indoor positioning system (IPS) for an industrial environment. The system is quite similar to Global positioning system (GPS). However, GPS can only work if the device is discovered by satellite. This work is to overcome the weakness of GPS capability for tracking an object that did not receive a satellite signal. The methods, technique and technology of tracking...
The lack of healthcare services in outback areas raises the need for efficient remote health monitoring systems. IEEE 802.15.6 standard defines a new wireless communication standard for healthcare systems to mitigate this problem. Power consumption is the most crucial dilemma in such system.

Energy consumption and energy modeling are important issues in designing and implementing of Wireless Sensor Networks (WSNs), which help the designers to optimize the energy consumption in WSN nodes. Good knowledge of the sources of energy consumption in WSNs is the first step to reduce energy consumption. Therefore, an accurate energy model is required for the evaluation of communication protocols...
Despite the deleterious effect of hardware impairments on communication systems, most prior works have not investigated their impact on widely used relay systems. Most importantly, the application of inexpensive transceivers, being prone to hardware impairments, is the most cost- efficient way for the implementation of massive multiple-input multiple-output (MIMO) systems. Consequently, the direction...
In a previous work of the authors, it was shown that I/Q imbalance in the transmitter and receiver chains significantly deteriorates the achievable amount of self-interference suppression. Having there only analytically and simulatively analyzed the effect of I/Q imbalance, this paper gives experimental results and additionally extends the algorithm to also correct for the I/Q imbalance at the receiver...
