1. A multiple-input-multiple-output wireless network, comprising:
- a first transceiver with M antennas;
wherein the first transceiver is configured to multiplex a data packet by a spatial multiplexing matrix and to transmit the spatially multiplexed data packet to a second transceiver;
wherein the first transceiver is reconfigurable to change the spatial multiplexing matrix to improve at least one characteristic of the transmission; and
wherein the second transceiver has N antennas.

Abstract
Techniques for enhancing the security and power efficiency of a multiple-input-multiple-output (MIMO) communication system are provided. In one embodiment, data packets are multiplexed by calculated spatial multiplexing matrixes (SMM). In one embodiment, the channel state information (CSI) is used to calculate a first transceiver'"'"'s SMM to optimize channel efficiency. In another embodiment, the CSI is used to calculate a first transceiver'"'"'s SMM to optimize channel secrecy.
