A Smart Antenna and Repeater Pattern Generation Method for an Optimal Base Station Automatic Search Repeater

摘要

The present invention relates to a smart antenna for a repeater that automatically tracks and receives an optimal base station signal while removing interference signals.;The present invention basically uses a smart antenna as the base station directional antenna 4 to generate the main beam of the antenna in the direction of one base station 1 in which the ratio of the pilot signal to the interference signal is largely received, A null pattern is generated in the signal direction of the other base stations 2 and 3 to provide a signal having a maximum pilot signal to interference signal ratio at all times.;According to the present invention, a smart antenna is used as the base station directional antenna 4 of the repeater 5 so that a maximum pilot signal is always transmitted regardless of the propagation environment change between the base stations 1, 2, and 3 and the base station directional antenna 4, The signal having the ratio of the signal to the interference signal is received, thereby improving the communication quality of the service area of the repeater 5 and improving the operation efficiency.
