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 ... -
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 ...
