INVESTIGATION INTO MIMO BASED COMMUNICATION FOR ENERGY-CONSTRAINED WIRELESS SENSOR NETWORK
Keywords:
Virtual MIMO, Cooperative MIMO, implementations, Multi-input multi-outputAbstract
In cooperative MIMO architectures, individual nodes with single antennas collaborate with each other to act as a MIMO unit. User-cooperative Multi-input multi-output systems have been generating significant interest due to their capacity/performance gains over Single-input single-output systems. So individual node complexity associated with traditional MIMO implementations is alleviated. This feature is especially beneficial in sensor networks and cellular systems where individual node energy, size and cost are important constraints. Cooperative MIMO schemes provide all the benefits of traditional MIMO systems.
