Experimental demonstration of bipolar codes for direct detection multi-user optical communication
We report the first experimental demonstration of a broadband spectral encoding and decoding technique using bipolar codes for optical code-division multiple access. The codeword correlations are verified and rejection of ...
Multiuser receivers for code-division multiple-access systems with trellis-based modulation
A code-division multiple-access (CDMA) communication system is studied where a trellis-based scheme is used for data encoding and modulation. The signature sequences (spreading codes), which are assigned to the direct-sequence ...
Real-Time Algorithms and Architectures for Multiuser Channel Estimation and Detection in Wireless Base-Station Receivers
This paper presents alogrithms and architecture designs that can meet real-time requirements of multiuser channel estimation and detection in future wireless base-station receivers. Sophisticated algorithms proposed to ...
VLSI implementation of the multistage detector for next generation wideband CDMA receivers
(Kluwer Academic Publishers, 2002-03-20)
The multistage detection algorithm has been proposed as an effective interference cancellation scheme for next generation Wideband Code Division Multiple Access (W-CDMA) base stations. In this paper, we propose a real-time ...
Multiuser detection in fast-fading multipath environments
We propose a new framework for multiuser detection in fast-fading channels that are encountered in many mobile communication scenarios. Existing multiuser RAKE receivers, developed to combat multipath fading and multiuser ...
Fixed Point Error Analysis Of Multiuser Detection and Synchronization Algorithms For CDMA Communication Systems
Conventional correlation based single-user techniques for Direct Sequence Code Division Multiple Access (DS-CDMA) wireless communication systems are susceptible to performance degradation due to interference from other ...
