Abstract
A highly spectral-efficient M-ary amplitude shift keying M-ary quadrature amplitude modulation orthogonal frequency division multiplexing (MASK-MQAM-OFDM) was proposed for the access network. With the highly spectral-efficient characteristic of MASKMQAM- OFDM, seamless integration among passive-optical network (PON), wireless fiber-to-the-antenna (FTTA), and optical wireless visible light communication (VLC) can be achieved without using extra bandwidth for different services. A proof-of-concept experiment was demonstrated. The relation between the spectral efficiency of the MASK-MQAM-OFDM and the upstream signal performance was also discussed.
