He was pursuing his Ph.D. degree under the supervision of Dr. Domingo Rodríguez.


  • Stochastic Acoustic Linear Time-Variant (SALT) Channel Characterization:

    My research addresses the fundamental question of how to characterize randomly time-varying channels when subjected to a special class of analytic signals as inputs; in particular, the class of multidimensional, multicomponent, polynomial phase (MMPP) signals.

    Analytic signal, implies the analytic representation of a real-valued function, assuming Hermitian symmetry. In general, an analytic signal or function is any function which can always be locally described by a convergent power series. Particular emphasis is given in this work to the characterization of randomly time-varying underwater acoustic (UWA) channels for broadband multiple input multiple output (MIMO) multi-carrier communication.
