Methods of Processing A Wireless Communication Signal, Wireless Communication Synchronization Methods, and A Radio Frequency Ideentification Device Communication Method

A method of processing a wireless communication signal comprising:

• providing a radio frequency identification device;
• receiving a data signal including a plurality of digital values within the radio frequency identification device;
• sampling the data signal at a plurality of moments in time during individual ones of the digital values using the radio frequency identification device;
• and
• wherein the sampling at one moment in time comprises sampling as a result of a transition in the data signal and the sampling at another moment in time comprises sampling after the elapse of a predetermined period of time without a transition in the data signal.

A wireless communication synchronization method comprising:

• receiving a data signal;
• generating a plurality of edge pulses corresponding to the data signal;
• generating a plurality of transitions within a clock signal as a result of a plurality of edge pulses during a first digital value of the data signal;
• generating a plurality of transitions within the clock signal during a second digital value of the data signal including generating at least one of the transitions independent of the edge pulses during the second digital value of the data signal;
• and
• sampling the data signal using the clock signal.
