This paper proposes a new multiple-input multiple-output (MIMO) eigenmode transmission technique in frequency selective multipath channels. The proposed scheme exploits the two-dimensioned (spatial and path domain) signal separability in frequemcy selective MIMO channels, for which different data streams are transmitted on each path component’s eigenmodes. A soft interference canceling minimum ...

We show how to construct an accelerator lattice cell that minimizes all intrinsic spin resonances. then apply this approach various toy electron and proton accelerators, considering, AGS-booster, AGS-like CEPC/FCC-ee, FCC-hh-like rings.

This paper describes a new microphone array technique and investigates its effectiveness for speech enhancement. A system structure consisting of a fixed near-field superdirective beamformer and an adaptive sidelobe canceling path is proposed (NFSD-ASC). The effect of adding a post-filter is also examined. The system is evaluated in terms of speech quality measures in the context of a computer ...

Fuel feeding and inhomogeneity of fuel typically cause process fluctuations in the circulating fluidized bed (CFB) process. If control systems fail to compensate for the fluctuations, the whole plant will suffer from fluctuations that are reinforced by the closed-loop controls. This phenomenon causes a reduction of efficiency and lifetime of process components. Therefore, domain experts are int...

Reliable estimation of users’ channels and data in rapidly time varying fading environments is a very challenging task of multiuser detection (MUD) techniques that promise impressive capacity gains for interference limited systems such as non-orthogonal CDMA and spatial multiplexing MIMO based LTE. This paper analyzes relative channel estimation error performances of conventional single user an...

In wireless relay networks, noise at the relays can be correlated possibly due to common interference or noise propagation from preceding hops. In this work we consider a parallel relay network with noise correlation. For the relay strategy of amplify-and-forward (AF), we determine the optimal rate maximizing relay gains when correlation knowledge is available at the relays. The effect of corre...
