Bandwidth-Efficient WDM-CAP-PON Using Digital Hilbert Single-Sideband Modulation
IEEE Photonics Journal, 2015 We propose a wavelength division multiplexing-carrier-less amplitude/phase modulation-passive optical network (WDM-CAP-PON) downstream with enhanced bandwidth efficiency using low-cost digital Hilbert single-sideband modulation.
