摘要
A linearized MIMO system which includes a MIMO receiver which comprises one or more receiving units, each receiving unit comprises one or more receiving antennas and an optional MIMO spatial decoder. The linearized MIMO system also includes a linearized MIMO transmitter, which comprises a plurality of non-linear power amplifiers at respective transmission branches, where each of the non-linear power amplifiers feeds a respective antenna with an amplified signal. The linearized MIMO system also includes a MIMO spatial pre-coder for receiving an artificial data signal from a global linearizer, and based on a channel state information of the medium (medium-channel), the linearized MIMO system creates a plurality of transmission branch-signals. Each of the branch signals feeds one of the non-linear power amplifiers, respectively. The global linearizer receives a data signal and creates the artificial data signal.
