Abstract: This disclosure provides systems, methods, and apparatus for an initial network acquisition process via multiple antennas. In one aspect a method of establishing communications via a wireless network at a wireless communications apparatus is provided. The method includes attempting an initial acquisition process, over one or more frequencies, for establishing communications over the wireless network via a transmit circuit and a receive circuit transmitting and receiving via a first antenna. The method further includes switching the transmit circuit and the receive circuit from transmitting and receiving via the first antenna to a second antenna in response to detecting failure of the initial acquisition process. The switching is independent of a performance metric of the first or the second antenna. The method further includes re-attempting the initial acquisition process based on the switching to the second antenna over the one or more frequencies.

Abstract: System and method for temperature-calibration of a crystal oscillator (XO) in a mobile device. A temperature-calibration status of the XO is determined and a trigger condition related to temperature-calibration of the XO is detected. If the temperaturecalibration status of the XO is not fully temperature-calibrated or if the XO has not been previously temperature-calibrated, a temperature-calibration session is initiated by an XO manager based on the condition, wherein a receiver is configured to receive signals and temperature-calibration of the XO is performed in a background mode based on the received signals. The condition based triggering ensures that the XO is temperaturecalibrated prior to launch of any position based or global navigation satellite systems (GNSS) based applications on the mobile device. The trigger condition can include first use or power-on, charging, presence in an outdoor environment, variation in operating temperature, pre-specified time, and/or user input pertaining to the mobile device.

Abstract: A method and apparatus for eliminating receive band noise in a communication system is provided. The method comprises sensing a transmit signal at a receive frequency, wherein the signal sensed is a bleed over signal from a transmit signal. The sensed bleed over signal is then digitized using a secondary receiver. This secondary receiver utilizes a separate path from the primary receive path. The next step in the method is to estimate the linear distortion, delay, attenuation in the sensed bleed over signal. Next, compensation for the linear distortion, delay, and attenuation are performed on the sensed bleed over signal. The sensed, digitized, and compensated bleed over signal is then cancelled from the primary receive path.
