Query: Shaped On-Off Keying Using Polar Codes   The probabilistic shaping scheme from Honda and Yamamoto (2013) for polar
codes is used to enable power-efficient signaling for on-off keying (OOK). As
OOK has a non-symmetric optimal input distribution, shaping approaches that are
based on the concatenation of a distribution matcher followed by systematic
encoding do not result in optimal signaling. Instead, these approaches
represent a time sharing scheme where only a fraction of the codeword symbols
is shaped. The proposed scheme uses a polar code for joint distribution
matching and forward error correction which enables asymptotically optimal
signaling. Numerical simulations show a gain of 1.8 dB compared to uniform
transmission at a spectral efficiency of 0.25 bits/channel use for a
blocklength of 65,536 bits.
