Abstract
A distributed radio system comprising a plurality of receivers (1,2,15), each receiver being adapted to receive radio signals and to transmit respective digital signals. The system further comprises a digital communication channel (3) coupled to the plurality of receivers (1,2,15) and adapted to receive the digital signals and to transmit the digital signals. The system comprises a base-band unit (4) coupled to the communication channel (3) and adapted to combine and process the digital signals, the digital signals comprising information available in each receiver (1,2,15) of the plurality of receivers for exploiting a diversity gain.
Claims15
A distributed radio system comprising:
- a plurality of distributed receivers not sharing a same oscillator, each receiver being adapted to receive a same radio signal and to transmit respective digital signals;
- a digital communication channel coupled to the plurality of receivers and adapted to receive the digital signals and to transmit the digital signals;
- a base-band unit coupled to the communication channel and adapted to combine and process the digital signals;
- wherein the baseband processing is split in such a way that further processing and combining of partly demodulated signals may be done in another unit while maintaining the diversity gain and the signal and a control data are exchanged over the digital communication channel;
- and
- the digital signals comprising information available in each receiver of the plurality of receivers for exploiting a diversity gain of the same radio signal.
A method of communication for a distributed radio system comprising steps of
- receiving a same radio signal via each of a plurality of antennas and a plurality of distributed receivers not sharing a same oscillator;
- digitizing and formatting the respective signals from each of the receivers;
- transmitting the digitized signals via a digital communication channel;
- processing the digitized signals in a base-band unit, wherein the baseband processing is split in such a way that further processing and combining of partly demodulated signals may be done in another unit while maintaining a diversity gain and the signal and a control data are exchanged over the digital communication channel.
