1. A signal processing device configured to process a baseband signal for wireless communication, the signal processing device comprising:
a plurality of temperature sensors associated with respective ones of a plurality of internal functional blocks of the signal processing device such that the plurality of temperature sensors are configured to sense a plurality of internal temperatures each associated with a respective one of the plurality of internal functional blocks of the signal processing device;
a storage device configured to store a plurality of thresholds defining a plurality of temperature ranges; and
a controller configured to,
estimate a surface temperature based on an artificial neural network trained according to training data including the plurality of internal temperatures and surface temperatures, and
selectively perform at least one thermal mitigation operation based on the surface temperature and the plurality of temperature ranges.
