Unary error correction (UEC) codes have recently been proposed for the joint source and channel coding of symbol values that are selected from a set having an infinite cardinality. However, the original UEC scheme requires the knowledge of the source probability distribution, in order to achieve near-capacity operation. This limits the applicability of the UEC scheme, since the source probability...
Irregular joint source and channel coding (JSCC) scheme is proposed, which we refer to as the irregular unary error correction (IrUEC) code. This code operates on the basis of a single irregular trellis, instead of employing a set of separate regular trellises, as in previous irregular trellis-based codes. Our irregular trellis is designed with consideration of the UEC free distance, which we characterize...
