    • Systems and methods for temperature-calibration of an uncompensated XO in a mobile device during mobile device operation. The XO is temperature-calibrated based on assistance from wireless signals, such as from satellite source, and optionally from terrestrial sources such as WWAN, CDMA, etc. Based on one or more received wireless signals received at a receiver, corresponding frequency estimates of the XO are obtained and correlated with corresponding operating temperatures in a processor. Based on one or more samples of frequency estimates and associated temperatures, the XO is temperature-calibrated in the processor wherein a frequency-temperature (FT) model is formulated for the XO. The frequency of the temperature-calibrated XO can be determined from the FT model at any given temperature.
    • 用于移动设备操作期间移动设备中未补偿的XO的温度校准的系统和方法。 基于来自无线信号(例如来自卫星源)和可选地从诸如WWAN,CDMA等地面源的无线信号进行温度校准。基于在接收机处接收到的一个或多个接收到的无线信号,相应的频率估计 获得XO并与处理器中的对应操作温度相关联。 基于频率估计和相关温度的一个或多个样本,XO在处理器中被温度校准,其中为XO制定了频率 - 温度(FT)模型。 温度校准XO的频率可以在任何给定温度下从FT模型确定。
