In numerous applications, these coefficients are required to satisfy certain restrictions, such as a bound on their dynamic range. Here, dynamic range refers to the ratio of the larges

For example, Fig. 1 shows how the surface distortion can deteriorate the gain performance of large antennas used for Deep Space exploration, which may result in the l

For example, Fig. 1 depicts the conceptual evolution of the Land Mobile Satellite System which is anticipated to evolve from utilizing approximately 6–9 meter reflectors to 55 meter reflectors in the era spanning the late 1980′s to early 2000. In order to commercially use these large, l

The maximum likelihood estimate of the angular coordinate is found, and the asymptotic variance of the estimate is calculated. The exact dis

Making Space for Cultural Entrepreneurshipls, requires synthesis in terms of harmonic constituents covering the range from high to low frequencies. Dispersive phenomena (i.e., frequency dependent propagation speeds of plane waves employed in the spectral-synthesis) usually play a minor role for the high frequency contribution and therefore

These descriptions exhibit a commonality with signal processing and model-based parameter estimation in terms both of sampling requirements, information content and system rank, and the role of difference-equation linear predictors.
