Measuring the physical layer performance of wireless communication systems: Part 33 in a series of tutorials on instrumentation and measurement
(Institute of Electrical and Electronics Engineers & Instrumentation and Measurement Society, 2011-10)
[Abstract]: Measuring the physical layer performance of wireless radio communication systems is one important step in clearly understanding their behavior in real-world, that is, non-simulation, environments. Unfortunately, ...
Evaluation of H.264/AVC over IEEE 802.11p vehicular networks
(SpringerOpen & European Association for Signal Processing, 2013)
[Abstract]: The capacity of vehicular networks to offer non-safety services, like infotainment applications or the exchange of multimedia information between vehicles, have attracted a great deal of attention to the field ...
Real-time multimedia coding and transmission
(SpringerOpen & European Association for Signal Processing, 2013)
[Abstract]: This paper sums up relevant topics covered by the special issue titled ‘Real-Time Multimedia Coding and Transmission’, including efficient content representation, multimedia transmission, hardware and software ...
DASBE: Decision-Aided Semi-Blind Equalization for MIMO Systems with Linear Precoding
(Akademie Ved Ceske Republiky * Ustav Informatiky, 2010)
[Abstract] Multiple-Input Multiple-Output (MIMO) digital communications standards usually acquire Channel State Information (CSI) by means of supervised algorithms, which implies a loss of performance since pilot symbols ...
A Novel Hybrid Approach to Improve Performance on Frequency Division Duplex Systems with Linear Precoding
(Springer, 2010)
[Abstrtact] Linear precoding is an attractive technique to combat interference in multiple-input multiple-output systems because it reduces costs and power consumption in the receiver equipment. Most of the frequency ...
A Real-Time Implementation of the Mobile WiMAX ARQ and Physical Layer
(Springer, 2015)
[Abstract] This paper presents an innovative software-defined radio architecture for the real-time implementation of WiMAX transceivers. The architecture consists of commercially available field-programmable gate array and ...
Design and implementation of an OFDMA-TDD physical layer for WiMAX applications
(SpringerOpen & European Association for Signal Processing, 2013)
[Abstract]: This work describes the design, implementation, and performance evaluation of an orthogonal frequency division multiple access (OFDMA) time-division duplexing (TDD) physical layer (PHY) compliant with the ...
Time-Modulated Multibeam Phased Arrays With Periodic Nyquist Pulses
(Institute of Electrical and Electronics Engineers, 2018-12)
[Abstract]: We present a single sideband time-modulated multibeam phased array governed by periodic Nyquist pulsed signals. A Nyquist pulse is a physically realizable approach to the ideal sinc function. Hence, its low-pass ...
Analog Beamforming Using Time-Modulated Arrays With Digitally Preprocessed Rectangular Sequences
(Institute of Electrical and Electronics Engineers, 2018-03)
[Abstract]: Conventional time-modulated arrays are based on the application of variable-width periodical rectangular pulses (easily implemented with radio frequency switches) to the individual antenna excitations. However, ...
Time-Modulated Phased Array Controlled With Nonideal Bipolar Squared Periodic Sequences
(Institute of Electrical and Electronics Engineers, 2019-02)
[Abstract]: Bipolar (±1) sequences with no zero state suit particularly well for safeguarding the switched feeding network efficiency when applied to time-modulated arrays. During the zero state of a conventional time-modulating ...
