Trade-Offs of Spatial Gain for QoS-Guaranteed Services in the MIMO Broadcast Channels
— Although the capacity of multiple-input multiple output (MIMO) broadcast channels (BCs) can be achieved by dirty-paper coding (DPC), it is difficult to apply the results direct...

ISI and ICI Suppression for Mobile OFDM System by Using a Hybrid 2-Layer Diversity Receiver
An OFDM system is very sensitive to orthogonality relation. For a mobile wireless system, it is impossible to avoid Doppler-induced inter carrier interference (ICI). Moreover, whil...
