DESCRIPTION About 1/3 of young adults between the ages of 16 and 20 are not literate enough in either reading advanced texts nor in reading comprehensive mathematical expressions with operators. As one of several explanations for this kind of "illiteracy", we take into account that the languages...

There are 21 time reference cells and 13 gain reference cells in the first DRM Plus symbol. These 34 reference cells of the first OFDM symbol in the trasmission frame are used for synchronization in frequency domain. An improved joint detection of frame, integer frequency offset, and spectral ...
and the received samples are applied to a slicer to yield the detected data symbols. Inter-symbol interference results from linear amplitude and phase dispersion in the channel that broadens the pulses and causes them to interfere with one another. The Nyquist criterion specifies a frequency-domain...
MAP receiver for high-speed numerical transmissions through rayleigh channels noisy and dispersive in time and frequency Specifically the a posteriori probability of the Markov chain of the states of the channel with intersymbolic interference are calculated recursively from the data received and from the...
Because the sound of the heart signal is not sparse in the time domain, we will observe the signal to make frequency range processing.The observation signal the obtained signal frequency range disperses row chart as shown in Figure after the fast Fournier transformation 3.[translate] ...
The device layer stack was grown on a standard 300 mm (001) Si substrate using RPCVD, showing potential for large-scale integration. Radio frequency (RF) characterization was performed using 2- μm RF optical measurement setup. To our knowledge, this is also the first PDs on Si with direct...
