Generalization of Channel Inversion Algorithms for Multiuser MIMO Downlink Systems
— 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...

Adaptive Resource Allocation Based on Channel Information in Multihop OFDM Systems
— 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...

Improving Goodput by Relaying in Transmission-Power-Limited Wireless Systems
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...

Optimal Channel Training in Uplink Network MIMO Systems
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...
