Abstract
The exemplary embodiment of the present invention provides a beam selecting apparatus of a fixed beam terminal, including: a delay time measuring unit which measures delay times of a plurality of signals received through a plurality of beams; a beam selecting unit which compares a threshold value selected based on the measured delay time and a signal strength of each of the plurality of signals to select a beam; and a switching type beam former which operates the plurality of beams in accordance with the selected beam.

A beam selecting apparatus of a fixed beam terminal, comprising:
- an initial synchronization obtaining means configured to obtain initial synchronization through the plurality of beams to determine an initial reception beam;
- a delay time measuring means configured to measure delay times of a plurality of signals received through a plurality of beams based on the obtained initial synchronization;
- a beam selecting means configured to compare a threshold value selected based on the measured delay time and a signal strength of each of the plurality of signals to select a beam;
- and
- a switching type beam former configured to operate the plurality of beams in accordance with the selected beam.
A beam selecting method, comprising:
- obtaining initial synchronization through the plurality of beams to determine an initial reception beam;
- measuring delay times of a plurality of signals received through a plurality of beams of a switching type beam former of a fixed beam terminal based on the obtained initial synchronization;
- selecting a threshold value for every signal based on the measured delay time;
- comparing signal strengths of the plurality of signals with threshold values selected for the plurality of signals;
- and
- selecting a beam which receives a signal of which strength is larger than the threshold value among the plurality of signals.
A beam selecting method, comprising:
- obtaining initial synchronization through a plurality of signals received through a plurality of beams of a switching type beam former of a fixed beam terminal to determine an initial reception beam;
- measuring signal strengths of the plurality of received signals to select a signal;
- measuring a delay time based on the initial synchronization obtained for the selected signal;
