In this paper, the authors examine the use of chaotic systems based on the iteration of 1-D and 2-D piecewise linear chaotic maps in a coded modulation scheme. In the proposed scheme, the transmitted information is imposed on the dynamics of the chaotic sy ...
Supercapacitor represent one of the newest innovations in the field of electrical energy rtorage, and are subject of several developments in the industry for many different and news applications. Supercapacitors, which can supply a high instantaneous power ...
For a general class of constant-energy trellis-coded modulation schemes with 2 ? states, necessary and sufficient conditions to guarantee that a maximum-likelihood sequence estimator can decode each symbol with a fixed delay of ? symbols are derived. Addit ...
DC-SQUIDs made of refractive materials NbN-MgO-NbN were prepared using thin film preparation techniques. The noise properties of these SQUIDs were investigated. The white energy sensitivity of typical devices is 600h (8mF0/ÃHz). The measured values are co ...
Pulse amplitude modulation scheme with the same spectral efficiency as QAM, that is twice the spectral efficiency of conventional PAM schemes, comprising the steps of: (1) forming a train of pulses q(t -kT/2) = p(t - k T/2)cos2 pi fo(t- k T/2), wherein p(t ...
Maximum likelihood detection is an essential part of high-performance multiple-input-multiple-output (MIMO) communication systems. While it is attractive due to its superior performance (in terms of BER) its complexity using a straightforward exhaustive se ...

Supercapacitors are new and powerful components for energy storage. Compared with batteries, the amount of energy they can store is low. But, as power sources they have the property to be re-loadable in a few seconds [1][2][3]. In that case, the needed ins ...
