Abstract :
We propose an original technique for the design of convolutional Tanner structures that are full diversity under iterative decoding. The code design is based on the analysis of the local trellis neighborhood and is suitable for transmission over wireless non-ergodic channels. This new technique enables us to split the giant convolutional checknode into multiple smaller checknodes which is a means to mimic the standard analysis of LDPC codes under iterative message passing decoding.
