Information Rates of Approximate Message Passing for Bandlimited Direct-Detection Channels
Daniel Plabst, Mohamed Akrout, Tobias Prinz +2
The capacity of bandlimited direct-detection channels is challenging to compute or approach due to the receiver non-linearity. A generalized vector approximate message passing (GVA…
Neural Network Equalizers and Successive Interference Cancellation for Bandlimited Channels with a Nonlinearity
Daniel Plabst, Tobias Prinz, Francesca Diedolo +4
Neural networks (NNs) inspired by the forward-backward algorithm (FBA) are used as equalizers for bandlimited channels with a memoryless nonlinearity. The NN-equalizers are combine…
Neural Network-Based Successive Interference Cancellation for Non-Linear Bandlimited Channels
Daniel Plabst, Tobias Prinz, Francesca Diedolo +4
Reliable communication over bandlimited and non-linear channels usually requires equalization to simplify receiver processing. Equalizers that perform joint detection and decoding…
Successive Interference Cancellation for Bandlimited Channels with Direct Detection
Tobias Prinz, Daniel Plabst, Thomas Wiegart +3
The maximum information rates for bandlimited channels with direct detection are achieved with joint detection and decoding (JDD), but JDD is often too complex to implement. Two re…
Comparison of PAM-6 Modulations for Short-Reach Fiber-Optic Links with Intensity Modulation and Direct Detection
Tobias Prinz, Thomas Wiegart, Daniel Plabst +6
PAM-6 transmission is considered for short-reach fiber-optic links with intensity modulation and direct detection. Experiments show that probabilistically-shaped PAM-6 and a framed…
Experiments on Bipolar Transmission with Direct Detection
Thomas Wiegart, Daniel Plabst, Tobias Prinz +6
Achievable information rates of bipolar 4- and 8-ary constellations are experimentally compared to those of intensity modulation (IM) when using an oversampled direct detection rec…
Multilevel Binary Polar-Coded Modulation Achieving the Capacity of Asymmetric Channels
Constantin Runge, Thomas Wiegart, Diego Lentner +1
A multilevel coded modulation scheme is studied that uses solely binary polar codes and Honda-Yamamoto probabilistic shaping. The scheme is shown to achieve the capacity of discret…
Achievable Rates for Short-Reach Fiber-Optic Channels with Direct Detection
Daniel Plabst, Tobias Prinz, Thomas Wiegart +5
Spectrally efficient communication is studied for short-reach fiber-optic links with chromatic dispersion (CD) and receivers that employ direction-detection and oversampling. Achie…
PAM-6 Coded Modulation for IM/DD Channels with a Peak-Power Constraint
Tobias Prinz, Thomas Wiegart, Daniel Plabst +4
Coded modulation with probabilistic amplitude shaping (PAS) is considered for intensity modulation/direct detection channels with a transmitter peak-power constraint. PAS is used t…
Design of Polar Codes for Parallel Channels with an Average Power Constraint
Thomas Wiegart, Tobias Prinz, Fabian Steiner +1
Polar codes are designed for parallel binary-input additive white Gaussian noise (BiAWGN) channels with an average power constraint. The two main design choices are: the mapping be…
Successive Cancellation List Decoding of BMERA Codes with Application to Higher-Order Modulation
Tobias Prinz, Peihong Yuan
BMERA or convolutional polar codes are an extension of polar codes with a provably better error exponent than polar codes. A successive cancellation (SC) decoding algorithm for BME…
Flexible IR-HARQ Scheme for Polar-Coded Modulation
Peihong Yuan, Fabian Steiner, Tobias Prinz +1
A flexible incremental redundancy hybrid auto- mated repeat request (IR-HARQ) scheme for polar codes is proposed based on dynamically frozen bits and the quasi-uniform puncturing (…
Polar Code Construction for List Decoding
Peihong Yuan, Tobias Prinz, Georg Böcherer +3
A heuristic construction of polar codes for successive cancellation list (SCL) decoding with a given list size is proposed to balance the trade-off between performance measured in…
Efficient Polar Code Construction for Higher-Order Modulation
Georg Böcherer, Tobias Prinz, Peihong Yuan +1
An efficient algorithm for the construction of polar codes for higher-order modulation is presented based on information-theoretic principles. The bit reliabilities after successiv…
