Abstract [en]

NOVELTY - The communication parameters are adapted for set of user terminals based on principle used for optimizing communication with respect to partial channel state information (CSI) by singular value decomposition (SVD). The parameters for another set of terminals, are adapted based on another principle to optimize multiple input and multiple output (MIMO) communication. The parameters are then sent to respective set of terminals. USE - For communicating between user terminals in multiple input multiple output (MIMO) based communication network (claimed). ADVANTAGE - Optimized communication between the user terminals is obtained effectively. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) transmitter node; and (2) multiple input multiple output based communication network. DESCRIPTION OF DRAWING(S) - The figure shows the schematic diagram of the SVD-based MIMO system. (Drawing includes non-English language text). scheduling unit (9') feedback channels (17,19) preprocessor (91) transmitter (T4)
