Resource allocation is an important strategy to optimize system performance in multiuser cooperative orthogonal frequency-division multiple-access (OFDMA) systems. In this paper, we jointly consider three different transmission modes in cooperative OFDMA systems, i.e., direct transmission (DT) mode, half-duplex (HD) relay cooperative transmission (HDRCT) mode, and full-duplex (FD) relay transmission...
Assortativity is an important structural characteristic of complex networks. In this paper, we propose a simple method to generate a network with the desired assortative coefficient but still keep the degree distribution unchanged. We simulate cases with different assortative coefficients and calculate the packet drop probability when the buffer size is limited. The simulation results indicate that...
