Adaptive nonlinear compensation for CDMA communication systems

This paper deals with nonlinear compensation in code-division multiple-access communications systems. We analyze the performance of the generalized cerebellar model articulation controller neural network in two problems: predistortion in nonlinear transmitters and adaptive interference cancellation in multiuser and multipath scenarios. Our examples demonstrate the performance of the compensator...

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...

Nonlinear Adaptive Blind Interference Cancellation for DS-CDMA Systems

In this paper we propose a multistage nonlinear blind interference cancellation (MS-NL-BIC) receiver for directsequence code-division multiple-access (DS-CDMA) systems. The receiver uses higher order statistics of the received baseband signal. Specifically, we use the second and fourth moments of the received signal to determine a component of the received vector that has significant mean energ...

Friction Compensation for Dynamic and Static Models Using Nonlinear Adaptive Optimal Technique

Friction is a nonlinear phenomenon which has destructive effects on performance of control systems. To obviate these effects, friction compensation is an effectual solution. In this paper, an adaptive technique is proposed in order to eliminate limit cycles as one of the undesired behaviors due to presence of friction in control systems which happen frequently. The proposed approach works for n...

An adaptive antenna array based propagation delay CDMA communication systems

This paper discusses the propagation delay estimation problem for DS-CDM4 based on an adaptive antenna array whzch can suppress interfering signals. The tap weights of the adaptzve beamformer are controlled by two adaptive algorithms such as direct matrzx inver.won (DM7) and linearly constrained minimum variance (LCW). The large sample maximum likelihood (ZSML) estimator is applied to the beamf...
