Outage Probability of Multiple-Input Single-Output (MISO) Systems with Delayed Feedback

, 2007
We investigate the effect of feedback delay on the outage probability of multiple-input single-output (MISO) fading channels. Channel state information at the transmitter (CSIT) is a delayed version of the channel state information available at the ...

Power allocation under per-antenna power constraints in multiuser MIMO systems

Tongxin xuebao, 2012
A low-complexity power allocation algorithm was investigated under per-antenna power constraints(PAPC)in multiuser multiple-input multiple-output (MIMO) systems.It was shown that the optimal power allocation subject to PAPC,aimed at maximizing the sum ...

Wireless Networks with Energy Harvesting and Power Transfer: Joint Power and Time Allocation

, 2016
In this paper, we consider wireless powered communication networks which could operate perpetually, as the base station (BS) broadcasts energy to the multiple energy harvesting (EH) information transmitters. These employ "harvest then transmit" mechanism,
