ACE Spectrum of LDPC Codes and Generalized ACE Design
The construction of good, finite-length, LDPC codes is currently an attractive research area. Reducing attention to the Binary Erasure Channel (BEC), this problem translates into t...

On the Growth Rate of the Weight Distribution of Irregular Doubly-Generalized LDPC Codes
In this paper, an expression for the asymptotic growth rate of the number of small linear-weight codewords of irregular doubly-generalized LDPC (D-GLDPC) codes is derived. The expr...

Application of Nonbinary LDPC Codes for Communication over Fading Channels Using Higher Order Modulations
Abstract— In this paper, we investigate the application of nonbinary low density parity check (LDPC) codes over Galois field GF(q) for both single-input single-output (SISO) and...

Symmetric LDPC codes are not necessarily locally testable
Locally testable codes, i.e., codes where membership in the code is testable with a constant number of queries, have played a central role in complexity theory. It is well known t...

Error Floors of LDPC Coded BICM
Abstract— In recent years performance prediction for communication systems utilizing iteratively decodable codes has been of considerable interest. There have been significant b...
