Latest Patents

Maddiotto holds a patent for a "Broad band digital radio receiver for multicarrier signal." This invention employs a quadrature demodulator to directly shift the radiofrequency signal into a base band. The local oscillator is strategically placed at the center of the radiofrequency bandwidth, allowing for the superimposition of channel pairs that are symmetric versus the frequency. The invention addresses base band equivocation through numeric-type second orthogonal demodulators, which provide pairs of twice-demodulated signals. These signals can be organized into four equation systems with four unknown values, consisting of in-phase and quadrature components of the two channels in each pair. The subsequent reconstruction networks effectively solve these systems, yielding the two components of each single channel for every pair. Additionally, one network within the receiver measures amplitude and phase dissymmetries in the analog demodulator's two branches, supplying four corresponding digital coefficients to the reconstruction network. This process counterbalances the effects of dissymmetry at the output.
