Amplitude-smoothed BPOF and amplitude-smoothed amplitude-encoded BPOF

SPIE Proceedings, 1990
In this paper smoothed binary phaseonly filtcr(ASBPOF) and amplitude smoothed amplitude encoded BPOF(ASAEBPOF) are presented. By computer simulation in the case of symmetrical and unsymmetrical characters it is concluded that with the BPOF and AEBPOF these filters sacrifice light efficiency due to the amplitudesmoothed factor it yield much better ...

Amplitude-only versus amplitude-phase estimation

IEEE Transactions on Instrumentation and Measurement, 1990
The feasibility of transfer function estimation based on amplitude-only measurements is investigated, and this method is compared with the amplitude-phase (full complex spectrum) method. It is shown that the amplitude-only-based method is a feasible alternative to the full complex spectrum method when the minimum in-phase transfer function of the ...

Probabilistic Amplitude Shaping

Foundations and Trends® in Communications and Information Theory, 2023
Summary: Probabilistic amplitude shaping (PAS) proposed in [\textit{G. Böcherer} et al., ``Bandwidth efficient and rate-matched low-density parity-check coded modulation'', IEEE Trans. Commun. 63, No. 12, 4651--4665 (2015; \url{doi:10.1109/TCOMM.2015.2494016})] is a practical architecture for combining non-uniform distributions on higher-order ...
