Distributed quasi-orthogonal space-time coding for two-way wireless relay networks by F.M. Abdurahman, A.M. Elazreg, Jonathon Chambers

“…Our end-to-end bit error rate simulations show that TW closed-loop D-QO-STBC and rotated open-loop D-QO-STBC are approximately 8 dB and 7.5 dB better than the distributed Alamouti TW approach at 10−4 bit error rate (BER), which confirms the advantage of four relay schemes in relay networks…”

Cooperative multi-hop wireless network with robustness to asynchronism by A.M. Elazreg, Shakiru K. Kassim, Jonathon Chambers

“…We compare the advantage in using direct transmission (DT) to assist in reducing the end-to-end bit-error-rate (BER) at the receiver with using multiple level cooperation among all nodes of each hop without direct transmission. …”

An Enhanced Feedback Scheme for Extended Orthogonal Space-Frequency Block Coded MISO-OFDM Systems by Nasr E.M. Eltayeb, Shakiru K. Kassim, Jonathon Chambers

“…However, we adopt a method which exploits the correlation among the feedback terms for the subcarriers, i.e. a group based quantization technique to reduce the feedback overhead significantly, rendering this scheme attractive to broadband wireless access systems.…”

Convolutional coding schemes with convenient power spectral density characteristics by Salvador Villarreal-Reyes

“…The signal model covers a wide variety of IR-based modulation schemes such as pulse position modulation (PPM), binary phase shift keying (BPSK), pulse amplitude modulation (P AM), biorthogonal PPM (BOPPM), PAMlPPM and pulse shape modulation (PSM), combined with periodic or random time hopping (TH) and/or direct sequence (DS) multiplication. …”

Inferring malicious network events in commercial ISP networks using traffic summarisation by Peter Sandford

“…In a laboratory environment, these metrics were used to detect DoS traffic representing as little as 0.1% of the overall network traffic. …”
