In many signal processing applications including Audio and speech processing as well as other research areas of diagnosis of failures in rotating machinery, finding a compact representation of observations signals is often highly desirable. In this respect, chirplets have recently been introduced as an efficient tool for signal representation. However,(More)
We present a new reliability-based hybrid automatic repeat request (RB-HARQ) scheme based on low density parity check (LDPC) codes. With the proposed RB-HARQ, which uses a rate-compatible LDPC code with puncturing and extending, the longest codeword is divided into clusters of code bits. Unlike previous works, in the event of a decoding failure, the(More)
