System And Method For Multi-Access Mimo Channels With Feedback Capacity Constraint
Systems And Methods Of Mimo Wireless Communication System With Partial Feedback Are Disclosed. In One Embodiment, A Base Station Estimates The Channel Matrices Of The K Mobile Units And Transmits An Index Value Corresponding To Each Of The Estimated Channel Matrix. Each Mobile Unit Selects A Power Control Matrix And Beam-Forming Matrix Based On The Received Index Value And Transmits Its Data Stream To The Base Station Using The Selected Power Control And Beam-Forming Matrix. A Method For Generating The Sets Of Power Control Matrices, Beam-Forming Matrices, And Partitions Of The Channel Matrix Space Is Disclosed.
