Abstract
An acoustic transmission device may communicate sensing data via one or more multiple-input multiple-output (MIMO) transmissions. The device may comprise a serial peripheral interface (SPI) and/or a phase shifting key (PSK) modulator. The device may be configured to provide a first SPI signal, perhaps including one or more coded information bits, to the PSK modulator. The device may provide a second SPI signal, perhaps including a synchronous clock signal, to the PSK modulator. The device may generate of one or more symbols on N transmit branches based on the first SPI signal. The device may generate of at least one carrier frequency with one or more phases to form one or more phased carriers based on the second SPI signal. The device may control a transmission of the sensing data (e.g., video) via the one or more symbols on the N transmit branches on the one or more phased carriers.
