[article]
2010
arXiv
pre-print
Preserved Fulltext
Zheng and Tse have shown that over a quasi-static channel, there exists a fundamental tradeoff, known as the diversity-multiplexing gain (D-MG) tradeoff. ...
In a realistic system, to avoid inefficiently operating the power amplifier, one should consider the situation where constraints are imposed on the peak to average power ratio (PAPR) of the transmitted ...
When examining these space-time codes, we find that these codes generally lead to high peak-to-average power ratio (PAPR) on each antenna. ...
