Low-density parity-check (LDPC) codes have attracted much attention over the past two
decades since they can asymptotically approach the Shannon capacity in a variety of data …

As one of the most classical data-storage systems, magnetic recording (MR) systems have
attracted a significant amount of research attention in the past several decades due to the …

In this paper, we propose a multiple-input multiple-output (MIMO) receiver algorithm that
exploits channel hardening that occurs in large MIMO channels. Channel hardening refers …

In this paper, based on the application of the sum-product (SP) algorithm to factor graphs
(FGs) representing the joint a posteriori probability (APP) of the transmitted symbols, we …

We optimize the random-like ensemble of irregular repeat-accumulate (IRA) codes for binary-
input symmetric channels in the large block-length limit. Our optimization technique is based …

Information theory, coding theory, and signal processing have significantly shaped magnetic
read/write channels engineering through a chronological sequence of innovations and …

Techniques for implementing message passing decoders, eg, LDPC decoders, are
described. To facilitate hardware implementation messages are quantized to integer …

We propose novel techniques to reduce the complexity of the well-known Bahl, Cocke,
Jelinek, and Raviv (BCJR) algorithm when it is employed as a detection algorithm in turbo …

In this paper, we propose computationally efficient yet near-optimal soft-output detection
methods for coded millimeter-wave (mmWave) multiple-input-multiple-output (MIMO) …

Density evolution (DE) is one of the most powerful analytical tools for low-density parity-
check (LDPC) codes and graph codes with message passing decoding algorithms. With …
