Abstract

In this work, we study the eigen-structure of the data covariance matrix in an asynchronous CDMA system. Our results reveal the joint effect of spreading codes and power control on warp converging Wiener filters. We further provide suggestions on spreading code selection and power control strategy in CDMA system design, where stable and predictable early convergence of the reduced-rank conjugate gradient Wiener filter (RRCG-WF) based multiuser detection (MUD) can be obtained.
