Maximum Achievable Constrained Power Efficiencies of MPPM- $L$ QAM Techniques
2015
IEEE Photonics Technology Letters
Preserved Fulltext
The maximum achievable power efficiency of a multipulse pulse-position modulation-L-ary quadratureamplitude modulation (MPPM-LQAM) technique under a constraint on its spectral efficiency is obtained. Variations to this technique that include polarization multiplexing and switching are considered as well. A simple characterization to the maximum achievable power efficiency is derived under the above constraint. Our results are compared with that of traditional QAM techniques under same
