In this paper, taking into account the multiple-input multiple-output (MIMO) systems experiencing log-normal shadowing fading, we investigate the ergodic capacity of such MIMO systems. For the MIMO fading channels with shadowing, using the Gauss Hermite integration, we present an approximated capacity expression. We also give a simplified and improved lower bound on the ergodic capacity by applying...
In this paper we derive optimal power allocation (PA) in space and time that minimizes BER for transmitter selection in multi-input-single-output (MISO) Rayliegh fading channels assuming perfect channel state information (CSI) is available at receiver and transmitter. This power allocation scheme achieves exponential diversity order with a single RF front end and requires feedback of the best channel...
The ergodic capacity of single input multiple output (SIMO) wireless communication systems over Nakagami-m fading channels is available in the literature for the case of identically independent distributed (i.i.d.) subchannels. However, the non- identically independent Nakagami-m case is more practical and has not been considered in the literature. In this paper, we derive an analytical expression...
