Systems and methods applicable, for instance, in wireless communications. For example, a wireless node and/or other computer may act to create a candidate signal list and/or may act to measure strength for one or more candidate list signals. As another example, the wireless node and/or other computer may act to calculate average difference between the strength of the strongest signal of the candidate list and the strength of a currently-received signal. As yet another example, the wireless node and/or other computer may act to perform one or more operations to employ the strongest signal of the candidate list in place of the currently-received signal.
