New MDS or Near-MDS Self-Dual Codes
Gulliver, T.A.,Jon-Lark Kim,Yoonjin Lee IEEE 2008 IEEE transactions on information theory Vol.54 No.9
<P>We construct new MDS or near-MDS self-dual codes over large finite fields. In particular, we show that there exists a Euclidean self-dual MDS code of length n = q over GF(q) whenever q = 2<SUP>m</SUP> (m ges 2) using a Reed-Solomon (RS) code and its extension. It turns out that this multiple description source (MDS) self-dual code is an extended duadic code. We construct Euclidean self-dual near-MDS codes of length n = q-1 over GF(q) from RS codes when q = 1 (mod 4) and q les 113. We also construct many new MDS self-dual codes over GF(p) of length 16 for primes 29 les p les 113. Finally, we construct Euclidean/Hermitian self-dual MDS codes of lengths up to 14 over GF(q<SUP>2</SUP>) where q = 19, 23,25, 27, 29.</P>
Performance Analysis of the Home M2M Cooperative Networks
Lingwei Xu,Hao Zhang,Tingting Lu,T A Gulliver 보안공학연구지원센터 2015 International Journal of Smart Home Vol.9 No.4
Based on decode-and-forward (DF) relaying scheme, the exact closed-form expression of the outage probability (OP) for the home mobile-to-mobile (M2M) cooperative networks over N-Nakagami fading channels is derived in this paper. Then the OP performance under different conditions is evaluated through numerical simulations. The numerical simulation results coincide with the theoretical results well, and the accuracy of the theoretical results is verified. The simulation results showed that: the fading coefficient, the number of cascaded components, the relative geometrical gain, and the power-allocation parameter have an important influence on the OP performance.
