Turbo Equalization with Coarse Quantization using the Information Bottleneck Method
Philipp Mohr, Jasper Brüggmann, Gerhard Bauch
This paper proposes a turbo equalizer for intersymbol interference channels (ISI) that uses coarsely quantized messages across all receiver components. Lookup tables (LUTs) carry o…

Memory-Assisted Quantized LDPC Decoding
Philipp Mohr, Gerhard Bauch
We enhance coarsely quantized LDPC decoding by reusing computed check node messages from previous iterations. Typically, variable and check nodes update and replace old messages ev…

Region-Specific Coarse Quantization with Check Node Awareness in 5G LDPC Decoding
Philipp Mohr, Gerhard Bauch
This paper presents novel techniques for improving the error correction performance and reducing the complexity of coarsely quantized 5G-LDPC decoders. The proposed decoder design…
