  • Patent number: 8938022
    Abstract: A system and method for realizing distributed interference alignment is disclosed. The system comprises a retrieving module, a determination module and a precoding module. The retrieving module retrieves source data. The determination module generates data describing one or more requirements for one or more associated Interference Alignment (IA) groups. The precoding module calculates a precoding vector based at least in part on the data describing the one or more requirements for the one or more associated IA groups. The precoding module is communicatively coupled to the retrieving module to receive the source data. The precoding module generates a transmission signal based at least in part on the precoding vector and the source data.

  • Publication number: 20140112410
    Abstract: A system and method for realizing virtual interference alignment. The system comprises a retrieving module, a determination module and a precoding module. The retrieving module retrieves source data. The determination module receives shared data and transmission information. The shared data and transmission information are generated from a shared signal received from one or more participating communication systems associated with a first virtual transmitting group. The precoding module calculates a precoding vector describing one or more requirements of interference alignment based at least in part on the transmission information. The precoding module generates a first transmission signal based at least in part on the precoding vector, the source data and the shared data.
