Abstract: Circuits and methods for using in parallel amplification and signal combining are described herein. A circuit uses a digitally controlled multistage cascade combiner, a digital phase and drive signal amplifier controller and a digital combiner controller circuit with N parallel signals with constant amplitudes belonging to an alphabet with M discrete values and discrete phases feeding it. The signals resulting from N power amplifiers (PAs) have also constant amplitudes belonging to an alphabet with N discrete values and discrete phases prior to being fed to the multistage combiner. A digital combiner controller circuit generates digital control information to activate, or deactivate, the outputs of the PAs, where a set of digital control signals generated in digital combiner controller are used to control sets of switches, where the signals can be activated at the combiner's inputs, according to their power and phase values.

Abstract: Certain embodiments involve generating and providing spatial audio using a predictive model. For example, a generates, using a predictive model, a visual representation of visual content provideable to a user device by encoding the visual content into the visual representation that indicates a visual element in the visual content. The system generates, using the predictive model, an audio representation of audio associated with the visual content by encoding the audio into the audio representation that indicates an audio element in the audio. The system also generates, using the predictive model, spatial audio based at least in part on the audio element and associating the spatial audio with the visual element. The system can also augment the visual content using the spatial audio by at least associating the spatial audio with the visual content.
