In this paper, a novel digital modulation technique based on spiking neuron models is proposed. Thanks to the extremely simple and low-power spiking neuron circuits, this modulation scheme allows a less complex receiver at the cost of a more complicated transmitter. Accordingly, it is a good candidate for downlink transmission. Since the transmitted signal is generated based on Shannon’s interp...

Advanced control algorithms using LQG and adaptive control techniques enable the design of an economically attractive alternative for conventional fin stabilizers and have proved to be robust during simulation experiments and full-scale trials. Abstract-This paper describes the design of an autopilot for rudder roll stabilization for ships. This autopilot uses the rudder not only for course kee...

Conventional methods for incorporating temporal information into speech features apply regression to a series of successive cepstral vectors to generate differential cepstra, or apply a cosine transform to generate cepstral-time matrices. This paper aims to generalise these techniques such that a series of stacked cepstral vectors is multiplied by a temporal transform matrix to produce the fina...

In this paper we obtain the conditions for L-convergence of the r-th derivatives of the cosine and sine trigonometric series. These results are extensions of corresponding Sidon’s and Telyakovskii’s theorems for trigonometric series (case: r = 0).

We present a novel cosine series representation for encoding fiber bundles consisting of multiple 3D curves. The coordinates of curves are parameterized as coefficients of cosine series expansion. We address the issue of registration, averaging and statistical inference on curves in a unified Hilbert space framework. Unlike traditional splines, the proposed method does not have internal knots a...

Interpolators have found widespread applications in communication systems such as multimedia. In this paper, the interpolated timing recovery employing raised cosine pulse for digital magnetic recording channel is investigated. This study indicates that the raised cosine interpolator with rolloff factor β between 0.4 and 0.6 is shown to have less aliasing effect and achieve better MSE performan...

We present a pricing method based on Fourier-cosine expansions for early-exercise and discretely-monitored barrier options. The method works well for exponential Lévy asset price models. The error convergence is exponential for processes characterized by very smooth (C[a, b] ∈ R) transitional probability density functions. The computational complexity is O((M − 1)N logN) with N a (small) number...

This work is a presentation of a new approach of robust watermarking applied in medical domain such as telemedicine hence the need to keep the visual aspect of medical images and other conservation of the various data substituted. For hiding information, the proposed method uses the Discrete Cosine Transform (DCT) space. To control identification and eventually the correction (if possible) of t...
