Aerodynamic Drum Magnetic Separator (ADMS) uses an adjustable air flow to enhance the separation of magnetic particles from gangue. In order explore matching relationship between field, and gravity as well capture behavior under action multi-physics, a related simulation model is established using finite element software COMSOL Multiphysics accuracy results verified by measurement, formula calc...

The problem of multiuser detection in wireless communications systems adopts, in flat-fading channels, a blind source separation (BSS) formulation of instantaneous linear mixtures. This contribution addresses the closed-form solutions to BSS in the complex-mixture scenario. The algebraic devices which span a unifying framework for the complex BSS closed-form estimators are developed. With the a...

This study addresses the problem of joint blind timing and carrier synchronisation in a (distributed-M ) × N antenna system where the objective is to estimate theM carrier offsets, theM timing offsets and to recover the transmitted symbols for each of theM users given only the measured signal at the N antennas of the receiver. The authors propose a modular receiver structure that exploits blind...

In this correspondence, we reply to the comments in Gu et al. [“Comments on ‘A blind signal separation method for multiuser communications,’” IEEE Transactions on Signal Processing, vol. 55, no. 5, pp. 2355–2356, May 2007]. We explain that the global convergence analysis of the method in Castedo et al. [“A blind signal separation method for multiuser communications,” IEEE Transactions on Signal...

The problem of multiuser interference cancellation in wireless cellular communication systems accepts a blind source separation (BSS) model. The present contribution studies the closed-form solutions to BSS in the real-mixture case. Connections among a number of seemingly disparate methods are unveiled, new procedures are put forward, and their asymptotic (large-sample) performance is analyzed....

We discuss lowering the order of the two-dimensional scalar-tensor R2 quantum gravity, by mapping the most general version of the model to a multi-dilaton gravity, which is essentially the sigma-model coupled with the Jackiw-Teitelboim-like gravity. In the continuation of our previous research, we calculate the divergent part of the one-loop effective action in a 2D scalar-tensor (dilatonic) gr...
