    On Rate-Compatible Punctured Turbo Codes Design

    We propose and compare some design criteria for the search of good systematic rate-compatible punctured turbo code (RCPTC) families. The considerations presented by S. Benedetto et al. (1998) to find the "best...

    An Efficient SF-ISF Approach for the Slepian-Wolf Source Coding Problem

    A simple but powerful scheme exploiting the binning concept for asymmetric lossless distributed source coding is proposed. The novelty in the proposed scheme is the introduction of a syndrome former (SF) in the s...

    Design of Three-Dimensional Multiple Slice Turbo Codes

    This paper proposes a new approach to designing low-complexity high-speed turbo codes for very low frame error rate applications. The key idea is to adapt and optimize the technique of multiple turbo codes to ...

    Turbo-per-Tone Equalization for ADSL Systems

    We study the equalization procedure in discrete multitone (DMT)-based systems, in particular, in DMT-based ADSL systems. Traditionally, equalization is performed in the time domain by means of a channel shorte...

    Iterative List Decoding of Concatenated Source-Channel Codes

    Whenever variable-length entropy codes are used in the presence of a noisy channel, any channel errors will propagate and cause significant harm. Despite using channel codes, some residual errors always remain...
