Method for efficient MU-MIMO transmission over the blind interference array system having a channel coherence time requirements with reduced

摘要

To use the (BIA) method blind interference sequences based on (MU-MIMO) [challenge] multi-user MIMO. The [SOLUTION] The wireless communication system includes a plurality of terminals, each terminal has a single RF chain can operate in antenna mode integer M, the terminal may shift in the antenna mode between M. To perform downlink transmission to multiple terminals by using a transmitter array of transmit antennas M, and the wireless communications system, and K from the transmitter arrays through L to (M + K-1) slot Using the BIA scheme based on MU-MIMO to use the codes BIA code subjected to terminal operable to communicate with one or more terminals, including one or more base stations, base station user The transmitted symbols in L k, and transmitted symbol of the L is through the individual slots of the M (M + D-1) Continuous slot L of the set.
