1. A method of operating an electronic device, comprising:
- providing a plurality of antenna elements;
evaluating a wireless communication performance criterion to obtain a performance evaluation;
assigning a first one of the plurality of antenna elements to a main wireless signal reception and transmission path and a second one of the plurality of antenna elements to a diversity wireless signal reception path based on the performance evaluation;
determining whether first and second communication channels associated with the main wireless signal reception path and the diversity wireless signal reception path, respectively, have changed; and
updating channel estimation models and/or multipath mitigation modules in a digital baseband signal processing section of the electronic device responsive to a determination that the first and second communication channels associated with the main wireless signal reception path and the diversity wireless signal reception path, respectively, have changed.
