Adaptive Zero-Padding OFDM over Frequency-Selective Multipath Channels
EURASIP Journal on Advances in Signal Processing, 2004 We present a novel bandwidth (BW) efficient orthogonal frequency division multiplexing (OFDM) scheme with adaptive zero-padding (AZP-OFDM) for wireless transmission. Redundancy issues in OFDM based on cyclic prefix (CP), zero-padding (ZP), as well as no

Federal Tax Competition and the Efficiency Consequences for Local Taxation of Revenue Equalization [PDF]
Recent work has shown that a system of equalization grants can limit tax competition among lower-level governments. The structure of such models, however, does not allow for the federal to be an active player but its role is being limited in the ...

Revenue Equalization Systems in a Federation with Tax Evasion [PDF]
We analyse how vertical or horizontal fiscal equalization affects the overprovision of local public goods due to vertical fiscal externality, when there is tax evasion.

Advanced Science, EarlyView.We present a large‐area bidirectional human–machine interface integrating electrostatic multimodal tactile sensing with a dual‐resonant haptic actuator. The system enables linear pressure sensing that is decoupled from actuation and stable broadband vibrotactile feedback under dynamic contact conditions, supporting real‐time feedback modulation aligned

Advanced Science, EarlyView.This work reports a strategy of engineering charge‐assisted hydrogen bonds to tailor charge transfer channels in HOFs, significantly improving their performance in photocatalytic H2O2 production. ABSTRACT The production of H2O2 via artificial photosynthesis is often limited by inefficient charge‐carrier separation, causing significant charge ...

GA Based Estimation of Sparse MIMO Channels with Superimposed Training
Elektronika ir Elektrotechnika, 2018 Multiple-input multiple-output (MIMO) techniques are foreseen to play a vital role in future 5G cellular networks. This paper presents a novel approach that employs genetic algorithm (GA) to estimate the sparse uplink MIMO channels using superimposed ...

Equalisation and Fiscal Competition [PDF]
The paper’s aim is to link two different issues: equalization and fiscal competition. In the model there are two regions: the first one has rich citizens and the other one has poor citizens.
