Abstract:
In order to improve the communication performance and communication reliability of an electronic device, a communication quality metric is determined based on information communicated via a wireless network using a single antenna. For example, the communication quality metric may be determined based on acknowledgment (ACK) and negative-acknowledgment (NACK) messages in the communicated information or a number of packets retransmitted and a number of new packets transmitted in the communicated information. Then, one of at least two antennas is selected based on the determined communication quality metric. In this way, the electronic device may effectively use a single receive chain to provide improved communication of the information.
