Distributed Linear Multiuser Detection in Cellular Networks

چکیده
We design a robust and computationally efficient iterative implementation of the Linear Minimum Mean Square Error (LMMSE) receiver for Wyner’s model of a linear cellular array. An important property of the the iterative LMMSE receiver is that each base station requires only local information to estimate its user’s signal. Analysis of the convergence of the iterative algorithm reveals a convergence rate that is insensitive to the array size, an important property for practical implementation. Conditions of convergence and the optimal step size to ensure fastest convergence are also determined.

Linear matrix inequality approach for synchronization of chaotic fuzzy cellular neural networks with discrete and unbounded distributed delays based on sampled-data control
In this paper, linear matrix inequality (LMI) approach for synchronization of chaotic fuzzy cellular neural networks (FCNNs) with discrete and unbounded distributed delays based on sampled-data controlis investigated. Lyapunov-Krasovskii functional combining with the input delay approach as well as the free-weighting matrix approach are employed to derive several sufficient criteria in terms of...
متن کاملBlind Adaptive Multiuser Detection with Averaging for Cellular Systems
In this paper, we consider blind adaptive multiuser detection in Correlated Waveform Multiple-Access (CWMA)based cellular radio networks. A common stochastic approximation (SA) based framework is proposed from which three blind adaptive algorithms for linear MMSE detection are obtained. Two of them coincide with previously proposed algorithms and the third is shown to be best suited for impleme...

Detecting anomalies is an important challenge for intrusion detection and fault diagnosis in wireless sensor networks (WSNs). To address the problem of outlier detection in wireless sensor networks, in this paper we present a PCA-based centralized approach and a DPCA-based distributed energy-efficient approach for detecting outliers in sensed data in a WSN. The outliers in sensed data can be ca...

In high dynamic conditions, using vector tracking loops instead of scalar tracking loops in GPS receivers is proved as an efficient method to compensate the performance. The Minimum Mean Squared Error detector as a multiuser detector is applied in the vector tracking loop for more reliability and efficiency. The Kalman filter does the two tasks of tracking and extracting the navigation data aft...
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...
