Signal Shaping for BICM at Low SNR [PDF]
, 2012 The mutual information of bit-interleaved coded modulation (BICM) systems, sometimes called the BICM capacity, is investigated at low signal-to-noise ratio (SNR), i.e., in the wideband regime. A new linear transform that depends on bits' probabilities is

Iterative Receiver Design for Probabilistic Constellation Shaping in ISI Channel
IEEE Access, 2020 This paper investigates the receiver design for probabilistic constellation shaping signaling over inter-symbol interference channel. The key component performing the constellation shaping is an adjustable distribution matcher, and the probabilistic ...

Cyclic division algebras: a tool for space-time coding [PDF]
, 2007 Multiple antennas at both the transmitter and receiver ends of a wireless digital transmission channel may increase both data rate and reliability. Reliable high rate transmission over such channels can only be achieved through Space–Time coding.

Benchmarking End-to-end Learning of MIMO Physical-Layer Communication [PDF]
, 2020 End-to-end data-driven machine learning (ML) of multiple-input multiple-output (MIMO) systems has been shown to have the potential of exceeding the performance of engineered MIMO transceivers, without any a priori knowledge of communication-theoretic ...

Short-range ultrasonic communications in air using quadrature modulation [PDF]
, 2009 A study has been undertaken of ultrasonic communications methods in air, using a quadrature modulation method. Simulations were first performed to establish the likely performance of quadrature phase shift keying over the limited bandwidth available in ...

Adaptive Turbo Equalization of Probabilistically Shaped Constellations
2023 Optical Fiber Communications Conference and Exhibition (OFC), 2023 Fiber nonlinearity compensation of probabilistically shaped constellations with adaptive turbo equalization is investigated for the first time. Potential for more than 100% transmission reach extension is demonstrated by combining probabilistic shaping, single-channel digital backpropagation, and adaptive turbo equalization.
