Abstract
The invention relates to a method for eliminating interferences for an interconnected group of base stations of a mobile radio network when receiving data transmitted by mobile radio terminals in the mobile radio network, wherein a) the data are encoded at the mobile radio terminal device as symbols of a modulation alphabet, and modulated at a carrier frequency for transmitting, b) information regarding the symbols received at the base station of the interconnected group are transmitted between the base stations by means of communication connections for eliminating interferences, and c) the base stations of the interconnected group demodulate and decode the received symbols in a cooperative and decentralized manner.

A method for eliminating of interference for an interconnected group of base stations of a mobile radio network when receiving data transmitted by mobile radio terminals in the mobile radio network, wherein
- a) the data are encoded in a mobile radio terminal as symbols of a modulation alphabet and modulated on a carrier frequency for the transmission,
- b) information regarding the symbols received at base stations of the interconnected group are transmitted between the base stations by means of communication links for eliminating interference, and
- c) the base stations of the interconnected group demodulate and decode the received symbols in a cooperative and decentralized manner,
- wherein
- d) a statistical expectation value of a received symbol is determined each time at a base station of the group and relayed as information for the eliminating of interference.
A base station in an interconnected group of base stations of a mobile radio network for eliminating of interference when receiving data transmitted by mobile radio terminals in the mobile radio network, comprising:
- a) a receiver for reception of the data which are encoded as symbols of a modulation alphabet and modulated on a carrier frequency for transmission in a mobile radio terminal,
- b) an interface for sending and receiving of information with regard to symbols received at base stations of the interconnected group by means of communication links for the eliminating of interference, and wherein
- c) the receiver is designed for cooperative and decentralized demodulation and decoding of received symbols together with other base stations of the group,
- wherein
- d) a determination module is provided for determining a statistical expectation value of a received symbol, wherein the statistical expectation value is relayed as information for eliminating of interference.
