Frequency-domain digital predistortion for Massive MU-MIMO-OFDM Downlink
Yibo Wu, Ulf Gustavsson, Mikko Valkama +2
Digital predistortion (DPD) is a method commonly used to compensate for the nonlinear effects of power amplifiers (PAs). However, the computational complexity of most DPD algorithm…
Generalized Spatially-Coupled Parallel Concatenated Codes With Partial Repetition
Min Qiu, Xiaowei Wu, Jinhong Yuan +1
A new class of spatially-coupled turbo-like codes (SC-TCs), dubbed generalized spatially coupled parallel concatenated codes (GSC-PCCs), is introduced. These codes are constructed…
On Doped SC-LDPC Codes for Streaming
Roman Sokolovskii, Alexandre Graell i Amat, Fredrik Brännström
In streaming applications, doping improves the performance of spatially-coupled low-density parity-check (SC-LDPC) codes by creating reduced-degree check nodes in the coupled chain…
On Product Codes with Probabilistic Amplitude Shaping for High-Throughput Fiber-Optic Systems
Alireza Sheikh, Alexandre Graell i Amat, Alex Alvarado
Probabilistic amplitude shaping (PAS) can flexibly vary the spectral efficiency (SE) of fiber-optic systems. In this paper, we demonstrate the application of PAS to bit-wise hard d…
Improving the Decoding Threshold of Tailbiting Spatially Coupled LDPC Codes by Energy Shaping
Thomas Jerkovits, Gianluigi Liva, Alexandre Graell i Amat
We show how the iterative decoding threshold of tailbiting spatially coupled (SC) low-density parity-check (LDPC) code ensembles can be improved over the binary input additive whit…
