Abstract :
We propose an algebraic framework that captures the parallelism of decoders for LDPC convolutional codes. From this framework, an architectural template of a decoding core is derived and its main aspects are discussed. Furthermore, sophisticated decoding structures are built using the decoding core as basic element.
