Randomness and metastability in CDMA paradigms
Jack Raymond, David Saad
Code Division Multiple Access (CDMA) in which the signature code assignment to users contains a random element has recently become a cornerstone of CDMA research. The random elemen…
The typical behaviour of relays
Roberto C. Alamino, David Saad
The typical behaviour of the relay-without-delay channel and its many-units generalisation, termed the relay array, under LDPC coding, is studied using methods of statistical mecha…
Inference by replication in densely connected systems
Juan P Neirotti, David Saad
An efficient Bayesian inference method for problems that can be mapped onto dense graphs is presented. The approach is based on message passing where messages are averaged over a l…
Statistical Mechanics Analysis of LDPC Coding in MIMO Gaussian Channels
Roberto C. Alamino, David Saad
Using analytical methods of statistical mechanics, we analyse the typical behaviour of a multiple-input multiple-output (MIMO) Gaussian channel with binary inputs under LDPC networ…
Minimizing Unsatisfaction in Colourful Neighbourhoods
K. Y. Michael Wong, David Saad
Colouring sparse graphs under various restrictions is a theoretical problem of significant practical relevance. Here we consider the problem of maximizing the number of different c…
Sparsely-spread CDMA - a statistical mechanics based analysis
Jack Raymond, David Saad
Sparse Code Division Multiple Access (CDMA), a variation on the standard CDMA method in which the spreading (signature) matrix contains only a relatively small number of non-zero e…
