Abstract :
Path pruning and its application to convolutional codes for unequal error protection (UEP), which result in path-compatible pruned convolutional (PCPC) codes, together with a cascaded implementation are proposed in this paper. Necessary and sufficient conditions are derived for a sub-class of PCPC codes whose decoding can be conducted via only a single decoder for the mother code
