Antenna subset selection at multi-antenna relay with adaptive modulation
Choi, Seyeong; Hasna, Mazen O.; Yang, Hong-Chuan; Alouini, Mohamed-Slim ( John Wiley & Sons, Ltd. , 2013 , Article)In this paper, we proposed several antenna selection schemes for cooperative diversity systems with adaptive transmission. The proposed schemes were based on dual-hop relaying where a relay with multiple-antenna capabilities ... -
Area spectral efficiency of infrastructure relay enhanced cellular systems
Zhu, Jun; Zhang, Lei; Yang, Hong?Chuan; Hasna, Mazen O. ( Institution of Engineering and Technology , 2016 , Article)In this study, the authors investigate the downlink area spectral efficiency (ASE) of infrastructure relay enhanced cellular systems. ASE for cellular systems is defined as the maximum achievable data rate per unit bandwidth ... -
Comparison of relaying strategies for cooperative diversity systems with adaptive modulation
Choi, Seyeong; Alouini, M.-S.; Yang, Hong-Chuan; Hasna, M.O. ( IEEE , 2009 , Conference Paper)In this paper, we propose several relay selection schemes for cooperative diversity systems with adaptive transmission. The proposed schemes are based on dual-hop relaying with multiple relays. We analyze the performance ... -
Effects of Post and Early Selection on SEC Based Transmit Diversity Systems with Linear Power Loading
Hasna, M.O.; Yang, Hong-Chuan; Alouini, Mohamed-Slim ( IEEE , 2008 , Conference Paper)Switch and examine combing (SEC) diversity scheme provides a lowest-complexity closed-loop transmit diversity solution. Furthermore, by probing sequentially available branches with different power loading levels, the SEC ... -
Generalized area spectral efficiency: An effective performance metric for green wireless communications
Zhang, Lei; Yang, Hong-Chuan; Hasna, Mazen O. ( IEEE , 2014 , Article)Area spectral efficiency (ASE) was introduced as a metric to quantify the spectral utilization efficiency of cellular systems. Unlike other performance metrics, ASE takes into account the spatial property of cellular ...
