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 ...

Modified Advanced Encryption Standard Algorithm for Reliable Real-Time Communications

Abu-Hudrouss, Ammar; ELTatar, Mahmoud (2018-09)

Ensuring the security of data while being transmitted or stored is a very important issue for companies and end users. Cryptography is used to transfer the data in a form that is not understood by anyone apart from the ...

Quadrature spatial modulation for wireless relaying networks

Muhareb, MS; Abu-Hudrouss, Ammar M.; Astal, Mohammed T (IEEE, 2018)

This article introduces a transmission protocol that adapts quadrature spatial modulation (QSM) into wireless relaying networks, in order to achieve better spectral efficiency and reliability compared to the state-of-art ...

Turbo-Coded V-BLAST/MAP MIMO System

Abu Hudrouss, Ammar M.; Al Habbash, Alaa H. (الجامعة الإسلامية - غزة, 2018)

Multiple Input Multiple Output (MIMO) systems can greatly increase the spectral efficiency. There is a need to design detection algorithm that can recover the transmitted signals with acceptable complexity and using suitable ...

Ldpc Code Construction using Randomly Permutated Copies of Parity Check Matrix

Abu-Hudrouss, Ammar; Lulu, Amro (2017-10-08)

A construction technique is proposed for low-density parity check (LDPC) codes. It uses a base parity check matrix designed from a ran-dom or constructed construction method as Gallager or Quasi-Cyclic LDPC (QC-LDPC) codes ...

Two-group decodable distributed differential space-time code for wireless relay networks based on SAST codes 2

Obada, Abdallah; Abu-Hudrouss, Ammar M. (2017)

Space-time code can be implemented in wireless relay networks when all relays cooperate to generate the code at the receiver. In this case, it is called distributed space-time code. If the channel response changes very ...

Set Partitioning to Construct Block Coded Modulation with the Presence of Spatial Modulation in MIMO Systems

Abu Hudrouss, Ammar M.; AbuFoul, Mohammed K. (الجامعة الإسلامية - غزة, 2016)

In this paper, enhancing the BER performance of multiple-input multiple-output systems (MIMO) is considered by using Block Coded Spatial Modulation (BCSM). It is a combination of Block Coded Modulation (BCM) used set ...
