Nonlinear 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 کاملComparing the performance of coded multiuser OFDM and coded MC-CDMA over fading channels
The bit error rate of a coded Multiuser OFDM (M-OFDM) system and coded Multicarrier CDMA (MC-CDMA) system with multiuser detection is analyzed. The paper focuses on downlink wireless applications, where the channel suffers from frequency-selective fading. We investigate both systems when long time interleaving is possible, though introducing large delays, and when time interleaving is limited. ...
متن کاملGenetic Algorithm Based Antenna Diversity Assisted Multiuser Detection for Synchronous CDMA Systems
|A spatial diversity reception assisted multiuser CDMA detector based on genetic algorithms (GAs) is proposed. Two di erent diversity selection strategies are considered. In our rst approach the so-called individuals of the GA are chosen for selection based purely on the sum of their corresponding gures of merit associated with the individual antennas, an approach which is analogous to employin...
متن کاملOn the Design and Performance of LDPC Coded MC-CDMA Systems
This paper presents and compares two different strategies for LDPC coded MC-CDMA system design. In general, Turbo multiuser detection is exploited by combining per-user MMSE-PIC detection and LDPC decoder together at the receiver end. First alternative, proposed earlier by the authors, is to apply the code across the substreams and transmit the coded data using MC-CDMA. The other approach, in t...
متن کاملMultiuser Detection for Cdma Systems with Nonlinear Modulation
Most past research on multiuser detection has focused on linearly modulated systems. This paper considers the more general problem of multiuser detection with nonlinear modulation. Our goals are to (a) gain fundamental insight into the capabilities of multiuser detection in such a setting, and (b) to provide practical algorithms that perform better than conventional methods. For the rst goal, w...
