Although the topic of multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) over different fading channels is well investigated, but its exact closed form symbol error rate (SER) expression employing orthogonal space-time block codes (OSTBCs) over uncorrelated Nakagami-m fading channels for M-ary phase shift keying (M-PSK) is still not available. The closed form expressions...
Ultra wideband (UWB) technology is one of the promising solutions for future short-range communication which has recently received a great attention by many researchers. However, interest in UWB devices prior to 2001 was primarily limited to radar systems, mainly for military applications, due to bandwidth resources becoming increasingly scarce and also its interference with other commutation networks...
Nonlinearity of high-power amplifier (HPA) plays a crucial role in the performance of multiple-input multiple-output (MIMO) systems. In this paper, we investigate the performance of MIMO orthogonal space-time block coding (STBC) systems in the presence of nonlinear HPA. Specifically, we assess the impact of HPA nonlinearity on the average symbol error probability (SEP), total degradation (TD), and...
