  • Patent number: 8744375
    Abstract: A wireless device may comprise a plurality of antennas that may be utilized during communications via various wireless interfaces. The wireless interfaces may comprise mobile interfaces, wireless personal area network (WPAN) interfaces, and/or wireless local area network (WLAN). The plurality of antennas may be utilized during a communication via a wireless interface in the mobile device. The mobile device may switch among antennas in the plurality of antennas utilizing one or more RF switches to enable utilizing best path for transmitted and/or received RF signals during the wireless communication. The mobile device may also perform signal combining of RF signals received via the plurality of antenna, and to enable a receiving end to perform signal combining of RF signals transmitted via the mobile device. A multiple-input-multiple-output (MIMO) combiner may be utilized to perform signal combing; the MIMO combiner may utilize maximal ratio combining to perform signal combining and equalization.
