Full-subcarriers Polar-OFDM for optical spectrum-efficient transmission exploiting Polarization Multiplexing

Optical polar based MIMO‐OFDM with fully generalised index‐spatial LED modulation

“…The CPT of the conventional OFDM signal relaxes the shaping problem of the complex OFDM time-domain signal [11,12,14,15]. The CPT operation removes the signs problem of the OFDM signal (i.e.…”

“…Moreover, in [11][12][13][14][15] the polar OFDM (POFDM) was introduced as spectrally and energy efficient modulation scheme for the VLC system. POFDM offered twice the ACO-OFDM data rate and improved the OWC system energy efficiency.…”
