Different Multiple Input Multiple Output Systems
The use of multiple antennas at the transmitter as well as at the receiver can greatly improve the capacity of a wireless link when operating in a rich scattering environment. In such an arrangement all transmitting antennas radiate in the same frequency band so the overall spectral efciency …

PERFORMANCE OF A ROBUST MULTIPLE-RING, MULTIPLE-TOKEN NETWORK
Analytical and simulation studies of multiple-ring Token Ring Networks (TRNs) in which all nodes are connected to all rings [4,5] show that the packet transfer delay improves with the number of rings connected to each node. However, such multiple-ring TRNs are not economically feasible as the cost …
