Abstract
The invention relates to a radio communications system comprising a base station, a digital exchange and a transmission system connecting said base station and said digital exchange. The base station comprises an antenna section, an RF receiver section for receiving an RF uplink signal from the antenna section, means for providing a digitised downconverted uplink signal from said received RF signal and means for transferring the digitised down converted uplink signal to said digital exchange through said transmission system. The digital exchange comprises means for receiving said digitised downconverted uplink signal and means for baseband processing of said digitised downconverted uplink signal.
Claims9
A radio communications system, comprising
- a base station;
- a digital exchange;
- and
- a transmission system connecting said base station and said digital exchange;
- said base station comprising
- an antenna section;
- an RF receiver section for receiving an RF uplink signal from the antenna section;
- means for providing a digitised downconverted uplink signal from said received RF signal;
- and
- means for sending the digitised downconverted uplink signal to said digital exchange through said transmission system;
- said digital exchange comprising
- means for receiving said digitised downconverted uplink signal;
- and
- means for baseband processing of said digitised downconverted uplink signal.
A radio communications system, comprising
- a base station;
- a digital exchange;
- and
- a transmission system connecting said base station and said digital exchange;
- said digital exchange comprising
- baseband processing means for providing a modulated multiplexed digital baseband signal from signals of several logical channels;
- and
- means for sending the modulated multiplexed digital baseband signal to said base station;
- said base station comprising
- means for receiving a modulated multiplexed digital baseband signal from said exchange;
- means for D/A converting said received signal;
- and
- an RF transmitter section for upconverting the D/A converted signal to an RF signal and transmitting said RF signal.
