Cooperative MIMO
In a multiuser (MU) multiple antenna system (MAS), a central processing unit is communicatively coupled to multiple distributed wireless terminals (WTs) via a network. The central processing unit processes channel measurements indicative of channel conditions between the multiple distributed WTs and a plurality of user devices and selects a plurality of WTs from the multiple distributed WTs to enhance channel space diversity within the MU-MAS. The central processing unit calculates (Multiple Input, Multiple Output) MIMO weights from the channel measurements for precoding a plurality of data streams that are transmitted concurrently from the plurality of WTs to the plurality of users, wherein the MIMO weights provide for a plurality of independent MIMO channels.

Cooperative subspace demultiplexing in content delivery networks
A source node selects a plurality of original data components to transfer to at least one destination node. A plurality of transmitting nodes cooperatively encodes the original data components to generate a plurality of subspace coded components and a corresponding code matrix. Each of the transmitting nodes transmits a subset of the plurality of subspace coded components and corresponding code matrix, wherein at least one of the transmitting nodes has a rank that is insufficient for decoding the plurality of subspace coded components. A destination node may employ a plurality of receiving nodes to cooperatively receive a plurality of subspace coded components and their corresponding code vectors, wherein the rank of at least one of the receiving nodes is insufficient for decoding the subspace coded components. The destination node builds up the dimension of the subspace spanned by code vectors it collects from the receiving nodes and then decodes the subspace coded components.
