Replica Analysis of Large-System CDMA
Overview This paper presents some new results on large-system CDMA obtained through the replica method developed in statistical physics. It is found that the spectral efficiency of randomly spread CDMA subject to Gaussian noise and flat fading in the large-system limit under arbitrary input distributions. Both joint decoding and single-user decoding are considered. In the latter case, a conditional mean estimator is first applied to separate the users and it is found that the resulting single-user channel for every user is equivalent to a Gaussian channel.

Space Division Multiple Access (SDMA) for Robust Ad Hoc Vehicle Communication Networks
This paper proposes a novel robust and self-organizing architecture for mobile ad hoc networks. The proposed architecture, Space Division Multiple Access (SDMA), relies on user position information and provides users...
Analysis of a Partial Decorrelator in a Multicell DS-CDMA System
Although the decorrelator has probably drawn more attention than any other multiuser detector, almost all studies have been for a single-cell code-division multiple-access (CDMA) system. In a CDMA system with...
