Transmit antenna switching
Abstract:
A wireless communication device may include a logic configured to select a first antenna as a transmitting antenna and a second antenna as a non-transmitting antenna; and to calculate a short-term antenna metric difference between the transmitting antenna and the non-transmitting antenna, a mid-term antenna metric difference between the transmitting antenna and the non-transmitting antenna, and a long-term antenna metric difference between the transmitting antenna and the non-transmitting antenna. The logic may be further configured to switch the second antenna to the transmitting antenna and the first antenna to the non-transmitting antenna, in response to determining that at least one of the calculated short-term antenna metric difference is greater than a short-term threshold, the calculated mid-term antenna metric difference is greater than a mid-term threshold, or the long-term antenna metric difference is greater than a long-term threshold.
