Renewable energies can enable embedded systems to be functional indefinitely. In particular for small autonomous sensors, energy harvesting techniques have attracted much interes...
— Recently a number of transmission schemes have been introduced to achieve sum capacity for multiuser multiinput multi-output (MIMO) broadcast channels (BC). A block diagonaliza...
— In this paper, we investigate the adaptive resource allocation problem in multiuser multihop OFDM systems. Assuming that base station(BS) knows all channel information, we form...
In wireless communication systems, the capacity of a cell (the amount of correctly delivered traffic in unit time) is a precious resource that can not be arbitrarily increased. T...
We consider a multi-cell frequency-selective fading uplink channel (network MIMO) from K singleantenna user terminals (UTs) to B cooperative base stations (BSs) with M antennas ea...
