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.
Claims20
A computer-implemented method for virtual interference alignment, the method comprising:
- retrieving source data;
- receiving shared data and transmission information, the shared data and the transmission information generated from a shared signal received from one or more participating communication systems associated with a first virtual transmitting group;
- calculating a precoding vector describing one or more requirements of interference alignment based at least in part on the transmission information;
- and
- generating a first transmission signal based at least in part on the precoding vector, the source data and the shared data.
A system for virtual interference alignment, the system comprising:
- a retrieving module retrieving source data;
- a determination module communicatively coupled to the retrieving module, the determination module receiving shared data and transmission information, wherein the shared data and the transmission information are generated from a shared signal received from one or more participating communication systems associated with a first virtual transmitting group;
- and
- a precoding module communicatively coupled to the determination module and the retrieving module, the precoding module calculating a precoding vector describing one or more requirements of interference alignment based at least in part on the transmission information and generating a first transmission signal based at least in part on the precoding vector, the source data and the shared data.
A computer program product comprising a non-transitory computer readable medium encoding instructions that, in response to execution by a computing device, cause the computing device to perform operations comprising:
- retrieving source data;
- receiving shared data and transmission information, the shared data and the transmission information generated from a shared signal received from one or more participating communication systems associated with a first virtual transmitting group;
- calculating a precoding vector describing one or more requirements of interference alignment based at least in part on the transmission information;
- and
- generating a first transmission signal based at least in part on the precoding vector, the source data and the shared data.
The computer program product claim of 16, wherein the second transmission signal is transmitted by one or more participating communication systems associated with a second virtual transmitting group.
