    In this paper we propose an innovative coded modulation scheme called "Accumulate Repeat Accumulate Coded Modulation" (ARA coded modulation). This class of codes can be viewed as serial turbo-like codes, or as a subclass ...

    In this paper we propose an innovative channel coding scheme called “Accumulate Repeat Accumulate codes” (ARA). This class of codes can be viewed as serial turbo-like codes, or as a subclass of Low Density Parity Check ...

    Repeat-Accumulate (RA) codes are the simplest turbo-like codes that achieve good performance. However, they cannot compete with Turbo codes or low-density parity check codes (LDPC) as far as performance is concerned. The ...

    Turbo codes not only achieve near Shannoncapacity performance, but also have decoders with modest complexity, which is crucial for implementation. So far efficient architectures for decoding of turbo codes have been proposed ...
