The quantum-dot cellular automata (QCA) is considered as an alternative tocomplementary metal oxide semiconductor (CMOS) technology based on physicalphenomena like Coulomb interaction to overcome the physical limitations of thistechnology. The decoder is one of the important components in digital circuits, whichcan be used in more comprehensive circuits such as full adde...

The capability of multilevel input ring-TCM coding scheme for generating high-rate codes with improved symbol Hamming and squared Euclidean distances is demonstrated. The existence of uniform codes and the decoder complexity are also considered.

This paper has developed a fast variable-length decoder which uses a plane separation technique to reduce the processing time of the feedback path in the decoder. The developed decoder performs two shift processes and a decision process concurrently. Therefore, the processing time in the feedback path of our developed variable length decoder can be improved and determined by the longest time am...

—In this letter, we propose parallel SC (Successive Cancellation) decoder and parallel SC-List decoder for polar codes. The parallel decoder is composed of) 1 (2   m M m component decoders working in parallel and each component decoder decodes a Polar code of a block size of M / 1 of the original Polar code. Therefore the parallel decoder has M times faster decoding speed. Our simulation resu...
