Reliability‐based quantization for soft decoding of LDPC codes in short‐reach optical links
IET Communications, Volume 16, Issue 1, Page 91-99, January 2022., 2022 Abstract Efficient quantizer design is vital in high‐speed optical receivers. In this paper, the authors propose a three‐level (1.5‐bit) reliability‐based quantizer for low‐complexity soft decoding of low‐density parity‐check (LDPC) codes, and show that it outperforms a conventional quantizer employing eight levels (3 bits).

Efficiently Computable Converses for Finite-Blocklength Communication
2022 IEEE International Symposium on Information Theory (ISIT), 2022 This paper presents a method for computing a finite-blocklength converse for the rate of fixed-length codes with feedback used on discrete memoryless channels (DMCs). The new converse is expressed in terms of a stochastic control problem whose solution can be efficiently computed using dynamic programming and Fourier methods.

An extended Fano's inequality for the finite blocklength coding [PDF]
2013 IEEE/CIC International Conference on Communications in China (ICCC), 2013 Fano's inequality reveals the relation between the conditional entropy and the probability of error . It has been the key tool in proving the converse of coding theorems in the past sixty years. In this paper, an extended Fano's inequality is proposed, which is tighter and more applicable for codings in the finite blocklength regime.
