1. A method, comprising:
determining, by a processor, a first voltage standing wave ratio (VSWR) during communications over a network; selecting, by the processor, a VSWR circle from among a group of VSWR circles based on the first VSWR; identifying, by the processor, a group of sets of tuning settings for variable reactance elements of a matching network, wherein the identifying of the group of sets of tuning settings is based on each set of tuning settings of the group of sets of tuning settings being positioned along a circumference of the VSWR circle; determining, by the processor, a VSWR threshold according to parameter information of the network; determining, by the processor, a group of second VSWR for the group of sets of tuning settings positioned along the circumference of the VSWR circle, wherein each of the group of second VSWR corresponds to one of the group of sets of tuning settings for the variable reactance elements; selecting, by the processor, a target set of tuning settings from among the group of sets of tuning settings responsive to a target second VSWR for the target set of tuning settings being a lowest second VSWR among the group of second VSWR; determining, by the processor, whether the target second VSWR for the target set of tuning settings satisfies the VSWR threshold; responsive to a first determination that the target second VSWR for the target set of tuning settings satisfies the VSWR threshold, adjusting the variable reactance elements of the matching network based on the target set of tuning settings; and responsive to a second determination that the target second VSWR for the target set of tuning settings does not satisfy the VSWR threshold, adjusting the variable reactance elements of the matching network based on a default set of tuning settings that is not included in the group of sets of tuning settings, wherein the default set of tuning settings is based on previous tuning settings utilized by the processor.
