Abstract

CDMA is an attractive scheme for multiuser communication. However, its performance is limited by the existence of multiple access interference energy (MAI), which results in the so called near-far problem. To reduce the MAI effect, different decorrelating structures for multiuser detection have been proposed. For the asynchronous receiver, several, of what is called `one-shot decorrelators' were proposed, among others, a decorrelator based on the inverse of the partial cross-correlation matrix and a blind adaptive algorithm, termed `Bootstrap decorrelator'. In most of these works, a flat fading environment was assumed. In this paper, we examine, analytically, as well as through simulation, the implementation of the one-shot bootstrap algorithm for use in a multi-path environment.
