  • Apparatus for convolutional self-doubly orthogonal encoding and decoding
    Patent number: 6167552
    Abstract: An encoder and decoder for generating and decoding convolutional codes of improved orthogonality. In an exemplary embodiment the encoder includes a K-bit length shift register for receiving an input serial stream of information bits and providing for each input bit a K-bit parallel output to a self-doubly orthogonal code sequence generator. The encoded symbol stream is threshold decoded iteratively using the inversion of the convolutional self-doubly orthogonal parity code generators.
