| 摘要 |
The invention relates to a linearized MIMO system which comprises: (a) a MIMO receiver which comprises one or more receiving units, each receiving unit comprises: (a.l) one or more receiving antennas; and (a.2) an optional MIMO spatial decoder and (b) a linearized MIMO transmitter, which comprises: (b.l) a plurality of non-linear power amplifiers at respective transmission branches, each of said non-linear power amplifiers feeding a respective antenna with an amplified signal; (b2) 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), creating plurality of transmission branch-signals, each of said branch signals feeding one of said non-linear power amplifiers, respectively; and (b3) said global linearizer receiving a data signal and creating said artificial data signal. |
