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...
In this paper, we propose a low-complexity switched soft demapper for rotated non-uniform constellation (e.g., nonuniform QAM, non-uniform APSK) DVB-NGH systems. The constellation would be twisted seriously through an I/Q independent fading channel. The requirement for two-dimensional (2D) soft demapping leads to the exponentially increased complexity. The proposed demapper classifies the received...
