Epistolas Varias que Consagra a la Catolica Magestad Del Rey D. Carlos Segundo, N.S. Monarca de las Espanas y del Nuevo Mundo, Don Felix de Lucio Espinosa y Malo, su autor, doctor en ambos derechos, con privilegio

Félix de Lúcio Espinosa y Maio, escritor e historiador espanhol, nasceu em Zaragoza, em 1646, e morreu em Palermo, Itália, em 1691. Doutorou-se em Direito na Universidade de Nápoles, foi Secretário do Conselho de Sua Majestade e Secretário de Estado e Guerra, no reino da Sicília. Cronista do reino de Aragão, das Índias e de Castela e Leão. Distinguiu-se por seu talento e sua cultura. ‘Epistolas varias...’ traz composições poéticas em forma de cartas, descrevendo entre outras coisas: ‘Del origem de las estatuas’, ‘De los sepulcros antigos’, ‘Del origem de las monedas’, ‘De la causa dei terremoto’, ‘Descripcion de la fiesta de toros de Madrid’, ‘De la velocidad dei tiempo’, ‘Consolatoria en la muerte’, ‘De la pintura, y alguns inventores’, ‘La paz y la union’, ‘Sobre eI origen de la poesia en varias naciones’

Model-based pilot and data power adaptation in psam with periodic delayed feedback

We consider the optimum design of pilot-symbol-assisted modulation (PSAM) schemes with feedback. The received signal is periodically fed back to the transmitter through a noiseless delayed link and the time-varying channel is modeled as a Gauss-Markov process. We optimize a lower bound on the channel capacity which incorporates the PSAM parameters and Kalman-based channel estimation and prediction. The parameters available for the capacity optimization are the data power adaptation strategy, pilot spacing and pilot power ratio, subject to an average power constraint. Compared to the optimized open-loop PSAM (i.e., the case where no feedback is provided from the receiver), our results show that even in the presence of feedback delay, the optimized power adaptation provides higher information rates at low signal-to-noise ratios (SNR) in medium-rate fading channels. However, in fast fading channels, even the presence of modest feedback delay dissipates the advantages of power adaptation.
