Optimal incorporation of sparsity information by weighted optimization
Toshiyuki Tanaka, Jack Raymond
Compressed sensing of sparse sources can be improved by incorporating prior knowledge of the source. In this paper we demonstrate a method for optimal selection of weights in weigh…
Optimal sparse CDMA detection at high load
Jack Raymond
Balancing efficiency of bandwidth use and complexity of detection involves choosing a suitable load for a multi-access channel. In the case of synchronous CDMA, with random codes,…
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…
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…
