When there are multiple candidates of diversity techniques applicable for a system, the diversity order can be used to roughly but quickly compare the techniques for a wide range of operating environments. For a system transmitting over frequency selective fading channels, th...

The results show that, for PULA systems, the channel capacity, which is boosted by beamforming diversity, can be determined using the channel gain, beam radiation pattern, and beamforming diversity order (BDO), where the BDO is dependent on the antenna characteristics and arr...

A space diversity reception technique presents effective method for increasing channel capacity and upgrading transmission reliability at relatively low cost. In this paper, wireless communication system with maximal‐ratio combining (MRC) microdiversity and selection comb...
 作者：Liang Yang 来源：[J].International Journal of Communication Systems(IF 0.712), 2013, Vol.26 (12), pp.1636-1642 摘要：SUMMARY(#br)Although there are many research results for the keyhole fading channels in the current literature, fewer results have investigated the antenna selection scheme and quantified the diversity order. In this letter, we first derive some simple statistics of the output...

In this network, the achievable diversity order is limited by the link between the source and the first relay. We derive the exact outage probability of fixed and selection relaying with spatial channel reuse, and demonstrate that applying selection relaying at the first rela...
 作者：Donghun Lee 来源：[J].Physical Communication, 2016, Vol.21, pp.70-76 摘要：... Using asymptotic analysis, we approximate the BER for the scheduled system, and quantify the diversity order and SNR gain, respectively. Analytical results show that the diversity order of the scheduled system is the product of spatial diversity (SD) and multiuser diversity (...
 作者：S. Kim 来源：[J].Electronics Letters, 2020, Vol.56 (5), pp.260-262 摘要：In this Letter, the authors analyse the diversity order of the precoding-aided spatial modulation (PSM) system with receive antenna subset (RAS) selection. It is shown that when there are $N_{\rm T}$ N T transmit antennas,...

Cooperative relaying is then employed over each sub‐channel to improve the system diversity order. We then investigate the asymptotic behavior of the outage probability and show that the proposed scheme achieves full diversity order in both amplify and forward (AF) and ad...

Although an...
