چکیده
|
Carrierless amplitude phase (cap) modulation format has appeared as a potential advanced modulation format candidate for spectrally efficient single-carrier modulation type due to less complexity and has competitive performance. in this paper,the comparison between 2d-cap-4 and 4-qam-dmt modulation format over 3 km single mode fiber (smf) transmission link using 1310 nm vertical cavity surface emitting laser (vcsel) has been performed for in-home network environment. the net bit rates of 625 mb/s and 454.6 mb/s are achieved for 2d-cap-4 and 4-qam-dmt,respectively. spectral efficiencies of 1.89 b/s/hz for 2d-cap-4 and 1.43 b/s/hz for 4-qam-dmt are reported. it is observed that 2d-cap-4 outperforms 4-qam-dmt with 1.14 db better receiver sensitivity. these results indicate that the privilege properties of cap modulation format can be an attractive prospect for in-home network environment.
