摘要
This paper investigates simultaneous transfer of information and energy over wireless link in the multiuser MIMO systems in which interference is aligned at the reduced signal subspace at each receiver. We propose to utilize interference that falls into the reduced subspace as an energy source, which was formerly discarded in the conventional interference alignment system. This makes the receive antenna selection achieve better rate and energy tradeoff. Therefore, the receive antenna selection is beneficial in order to partition the receive signal space into two orthogonal spaces for information and energy transfer.
