Introduction
Dimitrios Efstathiou is a notable inventor based in Greensboro, NC (US). He has made significant contributions to the field of communication technology, holding a total of 4 patents. His work focuses on advanced modulation techniques and reconfigurable communication systems.
Latest Patents
One of his latest patents is for a "Digital reconfigurable core for multi-mode base-band transmitter." This invention includes a digital pulse-shaping filter that performs pulse-shaping operations on a digitally modulated signal. It features a finite state machine that controls the operation and reconfiguration of the digital pulse-shaping filter. The design incorporates two memory units: one for storing coefficients and another for data. A multiplier is used to multiply data values with corresponding coefficients, while an adder accumulates the results. The finite state machine also reconfigures a look-up table value set in the first memory, which contains pre-stored pulse-shaped filtered waveforms.
Another significant patent is for "Universal signal modulators." This invention provides structures that are particularly useful for generating polar-modulated digital sequences from input phase and amplitude symbols. It also allows for the generation of quadrature-modulated digital sequences from input quadrature symbols. The modulation structure can be selected by changing the state of a mode command, offering flexibility in communication applications.
