A Comparison Between LDPC Block and Convolutional Codes

  title={A Comparison Between LDPC Block and Convolutional Codes},
  author={Daniel J. Costello and Ali Emre Pusane and Stephen Bates and Kamil Sh. Zigangirov},
LDPC convolutional codes have been shown to be capable of achieving the same capacity-approaching performance as LDPC block codes with iterative message-passing decoding. However, traditional means of comparing block and convolutional codes tied to the implementation complexity of trellisbased decoding are irrelevant for message-passing decoders. In this paper, we undertake a comparison of LDPC block and convolutional codes based on several factors: encoding complexity, decoding computational… CONTINUE READING
