Counting solutions for the CDMA multiuser MAP demodulator
J. P. L. Hatchett, Jun-ichi Inoue
We evaluate the average number of locally minimal solutions for maximum-{\it a-posteriori} (MAP) demodulation in code-division multiple-access (CDMA) systems. For this purpose, we…
Statics and dynamics of the Lebwohl-Lasher model in the Bethe approximation
N. S. Skantzos, J. P. L. Hatchett
We study the Lebwohl-Lasher model for systems in which spin are arranged on random graph lattices. At equilibrium our analysis follows the theory of spin-systems on random graphs w…
Dynamical replica theoretic analysis of CDMA detection dynamics
J. P. L. Hatchett, M. Okada
We investigate the detection dynamics of the Gibbs sampler for code-division multiple access (CDMA) multiuser detection. Our approach is based upon dynamical replica theory which a…
Dynamic rewiring in small world networks
J. P. L. Hatchett, N. S. Skantzos, T. Nikoletopoulos
We investigate equilibrium properties of small world networks, in which both connectivity and spin variables are dynamic, using replicated transfer matrices within the replica symm…
Finitely connected vector spin systems with random matrix interactions
A. Coolen, N. S. Skantzos, I. Perez Castillo +4
We use finite connectivity equilibrium replica theory to solve models of finitely connected unit-length vectorial spins, with random pair-interactions which are of the orthogonal m…
