Abstract
A portable terminal and a method operate multiple input multiple output (MIMO) antennas. Received signal strength indications (RSSIs) of the MIMO antennas are measured through a wireless communication unit that transmits and receives a wireless signal using the MIMO antennas. A path between a MIMO antenna with a greatest RSSI and a broadcast receiving unit is connected during a broadcast mode.

A method for operating a portable terminal with multiple input multiple output (MIMO) antennas, the method comprising:
- measuring received signal strength indications (RSSIs) of the MIMO antennas through a wireless communication unit that transmits and receives a wireless signal using the MIMO antennas;
- connecting a path between a MIMO antenna with a greatest RSSI and a broadcast receiving unit during a broadcast mode;
- and
- intercepting all paths between the MIMO antennas and the broadcast receiving unit upon receiving a broadcasting mode termination signal.
A portable terminal with multiple input multiple output (MIMO) antennas, the portable terminal comprising:
- a wireless communication unit configured to transmit and receive a wireless signal through the MIMO antennas;
- a broadcast receiving unit configured to receive a broadcasting signal through the MIMO antennas;
- a switch unit provided between the MIMO antennas and the broadcast receiving unit and configured to connect and intercept paths between the MIMO antennas and the broadcast receiving unit;
- and
- a controller configured to measure RSSIs of the MIMO antennas through the wireless communication unit, and control the switch unit to connect a MIMO antenna with a greatest RSSI and the broadcast receiving unit during a broadcast mode, wherein the controller is further configured to control the switch unit to intercept all paths between the MIMO antennas and the broadcast receiving unit upon receiving a broadcasting mode termination signal.
An apparatus in a portable terminal for operating a multiple input multiple output (MIMO) antenna, the apparatus comprising:
- a plurality of antennas of the MIMO antenna configured to transmit and receive wireless signals;
- a broadcast receiving unit configured to receive a broadcasting signal through the antennas during a broadcast mode;
- a wireless communication unit configured to transmit and receive wireless signals through the antennas and measure received signal strength indications (RSSIs) of the antennas;
- a switch unit configured to control a path between each MIMO antenna and the broadcast receiving unit;
- and
- a controller configured to control the switch unit according to the RSSIs of the antennas, to connect an antenna with a greatest RSSI and the broadcast receiving unit during the broadcast mode, to compare the RSSIs of the antennas with a reference value, and connect at least two antennas to the broadcast receiving unit when RSSIs of all the antennas are below the reference value.
