Channel-Estimating Apparatus and Mimo Communication System

MIMO communication-adapted communication equipment, comprising:

• an input unit operable to receive several pieces of channel information from a plurality of receivers, said plurality of receivers being operable to perform MIMO communication through a plurality of channels;
• an estimating unit operable to collectively estimate statuses of the plurality of channels in accordance with the several pieces of channel information received by said input unit, whereby estimation results are generated;
• and
• an output unit operable to feed the estimation results into said plurality of receivers.
