DEVICE AND METHOD FOR TIME DELAY FINE-TUNING UTP FEMTO DISTRIBUTION AND RELAY |
摘要 |
The present invention relates to fine-tuning a time delay of a relay device that distributes and relays a signal from a femto base station to several antennas by using an unshielded twisted pair cable (UTP). That is, by measuring a UTP time delay between a signal distribution device, which is a component of a UTP femto distribution and relay device, and a plurality of remote signal transmission and reception devices, respectively, a cable time delay between devices is corrected so that the plurality of remote signal transmission and reception devices may relay femtocell signals at the same time. A device for time delay fine-tuning UTP femto distribution/relay includes a signal distribution device that matches with a femtocell and measures a cable delay between the signal distribution device and the remote signal transmission and reception device, and the remote signal transmission and reception device that feeds a signal from the signal distribution device back and accesses a terminal and a femtocell signal wirelessly. |

1. A signal distribution device comprising:
a signal transmission unit matching a femtocell transmission signal to supply a transmission signal to a remote signal transmission and reception device; a signal reception unit calculating a feedback signal delay with the remote signal transmission and reception device based on the transmission signal fed back and received from the remote signal transmission and reception device, a signal from a terminal to be connected to a femtocell, and a signal from the signal transmission unit, removing the signal fed back, and relaying the signal from the terminal to the femtocell; and a signal distribution device control unit transmitting calculated signal delay information to the remote signal transmission and reception device. |
