A human centric communication network (HCCN) is a communication network offering human centric (or, social-network-based) mobile Internet services. This paper proposes a three-layer network architecture to model the relationship among users, their social groups, and the serving radio access networks for HCCN. Based on this model, several advertising(More)
One way of fully exploiting the channel capacity in multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) systems is to deploy precoding vectors derived from SVD to form parallel data pipes. Optimal precoding requires accurate channel state information for each OFDM subcarrier. This paper proposes a limited channel(More)
Multimedia broadcast/multicast service (MBMS) is one of the important services for 4th generation wireless communication systems. In this paper, we proposed a service architecture selection algorithm to find the best service architecture that maximizes the spectral efficiency of MBMS. Analytical models were presented to derive the average mutual information(More)
