Electronic device and method for multi-antenna communication apparatus

An electronic apparatus for a communication device, the electronic apparatus comprising:

• a processing circuit configured to:
• detect, according to a received signal and a plurality of reconstructed channels associated with a plurality of antennas of a counterpart multi-antenna communication device;
• a number of an activated reconstructed channel, so as to demodulate a first information bit from the counterpart multi-antenna communication device,
• wherein the first information bit is mapped to the activated reconstructed channel, the plurality of reconstructed channels being determined on the basis that a plurality of sets of reconstruction parameters configure the plurality of antennas of the multi-antenna communication device so that the plurality of reconstructed channels have low correlation with each other.

A method for a multi-antenna communication device, the method comprising:

• mapping a first information bit to a first reconstructed channel among a plurality of reconstructed channels associated with a plurality of antennas of the multi-antenna communication device;
• and
• providing a reconstruction parameter corresponding to the first reconstructed channel to reconstruct an actual channel from the multi-antenna communication device to a counterpart communication device to carry the first information bit,
• wherein the plurality of reconstructed channels are determined on the basis that a plurality of sets of reconstruction parameters configure the plurality of antennas of the multi-antenna communication device so that the plurality of reconstructed channels have low correlation with each other
