DS-CDMA Receiver Based on a Five-Port Technology
High data rates, low-power consumption, and low complexity will be the most important parameters in the design of the nextgeneration mobile terminals. In this paper we are introducing a new paradigm in the design of direct sequence spread spectrum receiver by combining analog and digital signal processing. Themain difference with respect to the conventional all-digital receiver design approach ...
متن کاملNonlinear Multiuser Receiver for Optimized Chaos-Based DS-CDMA Systems
Chaos based communications have drawn increasing attention over the past years. Chaotic signals are derived from non-linear dynamic systems. They are aperiodic, broadband and deterministic signals that appear random in the time domain. Because of these properties, chaotic signals have been proposed to generate spreading sequences for wide-band secure communication recently. Like conventional DS...
متن کاملChaotic Sequence Based DS-CDMA System With Space-Time Receiver
-Modern wireless communication systems require advanced signal processing techniques to optimise the system resources with increased performance and capacity. In this paper, a chaotic sequence based Direct Sequence Code Division Multiple Access system with space-time receivers is proposed to accommodate more number of users in a limited bandwidth as compared to conventional Pseudo-Noise (PN) se...

متن کاملA robust receiver for multi-user uplink DS-CDMA
This paper presents a robust receiver for uplink directsequence code-division multiple access (DS-CDMA) systems. The receiver uses low order auto-regressive models to approximate the multi-path fading channel taps, and a post correlation-based uncertain model for estimation purposes. keywords: RAKE receiver, Kalman filter, robust filter, multipath fading, multiuser detection.
