DOWNLINK MULTI-USER INTERFERENCE ALIGNMENT SCHEME

摘要

In the field of wireless communications, a method, system and device are provided for interference alignment on a downlink. The system uses a predetermined vector and channel knowledge from each transmitter to compute and feed back equivalent channel vector information from each receiver to its affiliated transmitter. With this information, each transmitter selects a set of affiliated receivers and constructs a transmitted signal by applying a selected precoding vector to rank 1 data, thereby eliminating interference to certain non-affiliated receivers.
