Cooperative MIMO is a new technique that allows disjoint wireless communication nodes (e.g. wireless sensors) to form a virtual antenna array to increase bandwidth, reliability and/or transmission distance. It differs fundamentally from other MIMO communication since the signals received from each node have a relative timing and frequency offset due to the distributed nature of their transmitting...
The authors consider a system architecture whereby orthogonal space time block codes (OSTBCs) are applied to a distributed set of wireless nodes. The utility offered is that by employing diversity we are able to greatly reduce the necessary link margin usually required to combat fast fading. A distributed set of wireless nodes are particularly well suited for this task as they are typically separated...
