Multiple-input multiple-output cloud transmission for high data rate local contents delivery

A novel cloud transmission (CTxn) technique is proposed on the basis of the multiple-input multiple-output (MIMO) technique, called MIMO CTxn. Applying a MIMO technique to conventional SISO CTxn provides a very efficient way to support high-date-rate service for delivering local content, even for a negative SINR. Simulation results show that the performance of MIMO CTxn is better than that of SISO CTxn while supporting high-order modulation and a high code rate.
