Description
Summary:A stream-oriented parallel concatenated convolutional (turbo) code (PCCC) is examined. The stream encoder uses continuous encoding with an interleaver constructed with using a tapped delay line. Stream decoding is envisioned using a pipeline of continuous decoding modules. The performance of the stream PCCC is examined and compared to a block-oriented scheme. The block interleaver design is addressed for continuous encoding and a class of non-block interleavers termed convolutional interleavers are considered.
