Abstract: Aspects of the disclosure are directed to interference cancellation and wireless communication. An analog active interference cancellation circuit may be configured to cancel in-device interference corresponding to transmissions from a transmitter at a wireless communication device, which affects the performance of a receiver at the wireless communication device. The interference cancellation circuit may be configured according to one or more digital coefficients calculated based on a baseband downconverted from the RF output of the receiver. That is, the digital coefficient may be converted to an analog coefficient and applied to the interference cancellation circuit.

Abstract: Methods, systems, and devices are described that provide for parameter adjustment for devices. A device may register a user profile associated with a user. During registration an image of the user may be captured and analyzed, such as to determine a size of facial features for the user. Also, during registration, metrics may be input or determined such as the age of the user or any sensory sensitivities. The device may capture a second image of the user. The second image may be compared to the first in order to determine the current distance between the user's face and the device. Comparing the first and second image may include comparing the size of corresponding facial features in each image, such as measured in pixels. Multiple images may be used for the first or second images. Based on contextual conditions and the distance, the device may adjust a sensory-related parameter.
