Abstract: An apparatus is disclosed for range-based transmission parameter adjustment. In an example aspect, the apparatus includes a first antenna, a second antenna, and a wireless transceiver. The wireless transceiver is coupled to the first antenna and the second antenna. The wireless transceiver is configured to transmit a proximity detection signal via the first antenna. The wireless transceiver is also configured to receive a reflected proximity detection signal via the second antenna. The reflected proximity detection signal including a portion of the proximity detection signal that is reflected by an object. The wireless transceiver is additionally configured to adjust a transmission parameter based on the reflected proximity detection signal. The transmission parameter varies according to a range to the object. The wireless transceiver is further configured to transmit an uplink signal using the transmission parameter.

Abstract: An apparatus for reducing spurs is described. The apparatus includes a coarse digital to analog converter (DAC). The apparatus also includes a correction term generator. The correction term generator generates a correction term. The correction term has an amplitude within a dynamic range of the coarse digital to analog converter (DAC). The apparatus also includes a baseband filter. The correction term is selected such that the baseband filter reduces the correction term to an amplitude approximating that of a spur in a transmit signal. The correction term is used to reduce a spur.
