TRANSMIT ANTENNA SELECTION SCHEMES FOR DOUBLE SPATIAL MODULATION

Asaati, Belal; Abu-Hudrouss, Ammar (2020-03-01)

Double spatial modulation (DSM) is a transmission technique which has been recently proposed for multipleinput multiple-output (MIMO) communication systems. DSM has a higher spectral efficiency compared with classical ...

Signed Quadrature Spatial Modulation for MIMO Systems

Abu-Hudrouss, Ammar M.; El Astal, M.-T.; Al Habbash, Alaa; Aissa, Sonia (Institute of Electrical and Electronics Engineers (IEEE), 2020)

Quadrature spatial modulation (QSM) was recently proposed to increase the spectral efficiency of spatial modulation. In QSM, the real and imaginary parts of a symbol are transmitted independently from different antennas. ...

Super-orthogonal double space-time trellis code

Tubail, Mohammed A.; Abu-Hudrouss, Ammar M.; El Astal, Mohammed (Elsevier BV, 2020)

This study develops a new class of super-orthogonal trellis codes for four transmit antennas based on double space-time codes. The transmit antennas are divided into two groups, each having two transmit antennas. The ...

Orthogonal frequency division multiplexing-based time difference of arrival estimation

Abudabbousa, Ahmad; Abu-Hudrouss, Ammar; Benlarbi-Delai, Aziz (The Institution of Engineering and Technology, 2019-09-17)

This study presents a spectral approach to estimate the time difference of arrival (TDOA) between a reference unit, composed of a pair of very close antennas (small baseline regarding the operating bandwidth), acting as a ...

Smart Traffic Lights using Image Processing Algorithms

Elkhatib, Mohammed M.; Adwan, Alarqam I.; Alsamna, Ahmed S.; Abu-Hudrouss, Ammar M. (Institute of Electrical and Electronics Engineers (IEEE), 2019-03)

Conventional methods of traffic light systems are unable to deal with the ongoing issues surrounding congestion. The current traffic light models are not suited to tackle problems such as traffic jams, ease of access for ...

Investigation of Non-Overlapping Time-Domain Windowing for OOB Radiation Reduction of OFDM System

Lulu, Amro; Abu-Hudrouss, Ammar M. (Institute of Electrical and Electronics Engineers (IEEE), 2019-03)

Orthogonal frequency-division multiplexing (OFDM) systems suffer from significant out-of-band (OOB) radiation. All existing techniques have several drawbacks as wasting spectral or time resources. Time domain windowing is ...

On Using Quadrature Spatial Modulation in Multi-User Networks

El Astal, Mohammed; Al Habbash, Alaa; Abu-Hudrouss, Ammar M. (Institute of Electrical and Electronics Engineers (IEEE), 2019-03)

Quadrature spatial modulation (QSM) has been recently proposed for MIMO communication systems. It comes to enhance the overall throughput over conventional spatial modulation (SM) techniques. This article investigates the ...

Space-time transmission scheme for asynchronous cooperative communications networks

El Astal, Mohammed; Al Habbash, Alaa; Abu-Hudrouss, Ammar M. (Institute of Electrical and Electronics Engineers (IEEE), 2019-03)

In this paper, an effective transmission scheme is proposed for asynchronous cooperative networks with two relays. The need for synchronization is obviated by allowing a single relay to be active in each time-slot of the ...

Improved Super-Orthogonal Trellis-Coded Spatial Modulation Using STBC-CSM

Abu-Hudrouss, Ammar M. (2018-12)

Trellis coded modulation (TCM) is a scheme that enhances the error performance without extra power not bandwidth. This paper presents a modified Super-Orthogonal Trellis-Coded Spatial Modulation (SOTC-SM) based on a cyclic ...

Comparative Study for the Performance of VBLAST, QOSTBC and Hybrid BLAST-STBC MIMO System under Transmit Link Deep Fading

Salemdeeb, Mohammed; Abu-Hudrouss, Ammar M. (2018-09)

This paper studies the effect of transmit antenna multipath channel deep fading on the effective received signal-to-noise ratio (SNR), bit error rate (BER), capacity and throughput of 4 × 4 MIMO system for several transmit ...
