Equalization with oversampling in multiuser CDMA systems [PDF]
, 2004 Some of the major challenges in the design of new-generation wireless mobile systems are the suppression of multiuser interference (MUI) and inter-symbol interference (ISI) within a single user created by the multipath propagation. Both of these problems

Interference-Free Broadband Single- and Multi-Carrier DS-CDMA
, 2005 The choice of the direct sequence spreading code in DS-CDMA predetermines the properties of the system. This contribution demonstrates that the family of codes exhibiting an interference-free window (IFW) outperforms classic spreading codes, provided ...
