Abstract: A method of collecting physiological parameter data of a monitored subject comprises measuring a biosignal from which the physiological parameter is deducible, including noise; converting the noisy measured biosignal to a vector having different frequency components with corresponding magnitude coefficients; discarding select frequency components with coefficients below a prescribed threshold; and communicating the reduced vector to a computing device for processing to deduce the physiological parameter. A method of processing physiological parameter data comprises receiving a measured biosignal with electromagnetic interference noise; obtaining from the noisy measured biosignal representative data using a machine learning algorithm; and determining the physiological parameter from the representative data.

Abstract: The invention is directed to systems and methods for quadrature spatial modulation in the transmission of over a wireless network. A plurality of transmit antennas are configured in a spaced apart configuration, with each antenna representative of a spatial constellation symbol comprising an in-phase component and a quadrature component. A transmission unit is configured to map source data to the spatial constellation symbol of the transmit antennas, and to transmit a carrier signal comprising the in-phase and quadrature components out of phase. At least one receiving antenna is configured to receive the carrier signal, and at least one receiving unit is configured to demodulate the carrier signal to generate the source data.
