TABLE I: Complexity of variable and check nodes. - "Uniform vs. Non-Uniform Coarse Quantization in Mutual Information Maximizing LDPC Decoding"
We design the uniform quantizers in order to maximize the generalized mutual information (GMI) on the combined LLR over all MTs under the backhaul constraint.
This paper uses the reconstruction-computation-quantization (RCQ)paradigm to decode low-density parity-check (LDPC) codes. RCQ facilitates dynamic non-uniform ...
The other way to realize non-uniform quantization is by designing quantization parameters that maximize the mutual information between the source and quantized ...
In this paper, we propose a finite alphabet iterative decoder (FAID) named rate-compatible mutual-information-maximizing quantized shuffled min-sum ...
Quantizers aiming to maximize mutual information are widely used in non-uniform quantization ... decoders that do not perform coarse non-uniform quantization,.
Abstract—We investigate iterative low-resolution message- passing algorithms for quasi-cyclic LDPC codes with horizontal and vertical layered schedules.
