Abstract: Methods and wireless communication devices for processing wireless signals with adaptive frequency shift correction. An embodiment of the method includes receiving a wireless signal by the receiver, performing packet detection to detect at least a portion of a preamble part of a current frame carried in the wireless signal according to a default frequency output from a Phase Lock Loop (PLL), estimating a frequency offset between the default frequency and a frequency used to carry information in the preamble part of the current frame, reconfiguring the PLL according to the frequency offset to output a compensated frequency, and processing a packet part of the current frame using the compensated frequency output from the PLL. The method may further mitigate the impact of a residual Direct current (DC) component by filtering the wireless signal based on the compensated frequency.

Abstract: Methods of printing metallic objects include providing parameters of an object for printing, and controlling a deposition of a fluid metallic material to form the object. At least an outer surface region of the fluid metallic material is converted to a solid region after deposition.
