摘要
In this paper. a new nonlinear processing algorithm for the suppression of a narrowband interference in direct sequence spread spectrum systems is introduced. The proposed algorithm has an advantage in that the unknown interference parameters are accurately identified by processing data in a block-by-block basis via the well established signal subspace techniques. The performance of a receiver that employs such an interference suppression algorithm is evaluated in terms of the signal-to-noise ratio (SNR) improvement. Comparisons to the existing nonlinear methods are also presented. (C) 1999 Elsevier Science B.V. All rights reserved.
