The bootstrap algorithm for a one-shot matched filtering multiuser detector in a multipath environment

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 the `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 multipath environment
