Discrete Hartley matrix transform precoding-based OFDM system to reduce the high PAPR
ICT Express, 2019 The high peak-to-average power ratio (PAPR) is one of the major drawbacks of the orthogonal frequency division multiplexing (OFDM) systems that make non-linear distortion in practical implementation of high power amplifier (HPA).

On the Hadamard product of Hopf monoids
, 2012 Combinatorial structures which compose and decompose give rise to Hopf monoids in Joyal's category of species. The Hadamard product of two Hopf monoids is another Hopf monoid. We prove two main results regarding freeness of Hadamard products.

On the Method of Harmonic Balance for Lumped‐Element Transformer Models
International Journal of Circuit Theory and Applications, EarlyView.The steady‐state solution of a lumped‐element transformer model with a dry friction‐like hysteresis model depicting the magnetic core is of interest. The harmonic balance method efficiently solves this stiff system. We derive the harmonic balance algorithm, enhance it with performance and convergence improvements, and demonstrate its efficiency by ...

Universal quantum computation with unlabeled qubits
, 2006 We show that an n-th root of the Walsh-Hadamard transform (obtained from the Hadamard gate and a cyclic permutation of the qubits), together with two diagonal matrices, namely a local qubit-flip (for a fixed but arbitrary qubit) and a non-local phase ...

Online Cyber‐Physical Neural Network Model for Real‐Time Hybrid Simulation
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Real‐time hybrid simulation (RTHS) is an experimental testing methodology that divides a structural system into an analytical and an experimental substructure. The analytical substructure is modeled numerically, and the experimental substructure is modeled physically in the laboratory. The two substructures are kinematically linked together at

Galerkin Finite Element Method for Caputo–Hadamard Time-Space Fractional Diffusion Equation
MathematicsIn this paper, we study the Caputo–Hadamard time-space fractional diffusion equation, where the Caputo derivative is defined in the temporal direction and the Hadamard derivative is defined in the spatial direction separately.

Complex Hadamard Matrix-Aided Generalized Space Shift Keying Modulation
IEEE Access, 2017 In this paper, we present a complex Hadamard matrix-aided generalized space shift keying (HSSK) modulation scheme, which introduces complex-Hadamard-based signal vectors at the transmitter to provide higher spectrum efficiency than generalized space ...

Deep Learning for Bond Yield Forecasting: The LSTM‐LagLasso
International Journal of Finance &Economics, EarlyView.ABSTRACT We present long short‐term memory (LSTM)‐LagLasso, a novel explainable deep learning approach applied to bond yield forecasting. Our method involves feature selection from a large universe of potential features and forecasts bond yields using dynamic LSTM networks.
