Random Sign Repetition Time-Hopping UWB with Multiuser Detection

open access: yesEURASIP Journal on Wireless Communications and Networking, 2005
A modified time-hopping (TH) ultra-wideband (UWB), called the random sign repetition TH-UWB, is considered to improve the performance of the minimum mean square error (MMSE) multiuser detector.

Space-Time Coded MC-CDMA: Blind Channel Estimation, Identifiability, and Receiver Design

open access: yesEURASIP Journal on Advances in Signal Processing, 2002
Integrating the strengths of multicarrier (MC) modulation and code division multiple access (CDMA), MC-CDMA systems are of great interest for future broadband transmissions. This paper considers the problem of channel identification and signal combining/

Turbo Multiuser Detection Architectures.

open access: yes, 2003
The discovery of Turbo Codes in 1996 by Berrou et. al. proved to be a huge boost for the research of channel coding. The Turbo Principle behind turbo codes was found to be applicable in other areas. One of these areas is Multiuser Detection. In this thesis, Turbo Multiuser Detection is investigated in order to answer two main questions.

Blind Multi-User Equalisation for a Dispersive DS-CDMA Downlink under Carrier Frequency Offset Conditions [PDF]

open access: yes, 2004
We address blind multiuser detection in a DS-CDMA downlink channel in the presence of carrier frequency offset. The synchronous users are separated by re-establishing orthogonality of their spreading sequences in a shared equaliser at the chip level. The
