A User-Centric Approach for Dynamic Resource Allocation in CDMA systems based on Hopfield Neural Networks

چکیده
This paper introduces a novel approach for considering the Dynamic Resource Allocation (DRA) in a multi-rate DS-CDMA wireless network supporting non realtime (NRT) communication. The allocated bit rate obeys to a user-centric approach by introducing a non-satisfaction user probability that has to be maintained below its targeted value while still keeping the best exploitation of the maximum available bandwidth. To this purpose different classes of users with different Contracted User Profiles are introduced and a Hopfield Neural Network optimization methodology is used under both user and network restrictions. Significant and promising results are finally shown for a single isolated cell DSCDMA scenario including realistic propagation and mobility models.

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...
