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 study introduces a training pipeline comprising two components: the Encoder-Decoder-Outlayer framework and Vector Space Diversification Sampling method. efficiently separates pre-training fine-tuning stages, while sampling method employs pivot nodes to divide subvector space selectively choose unlabeled data, thereby reducing reliance on human labeling. The offers numerous advantages, incl...

This paper extends recent results on steganographic capacity. We derive capacity expressions for perfectly-secure steganographic systems. The warden may be passive, or active using a memoryless attack channel, or active using an arbitrarily varying channel. Neither encoder nor decoder know which channel was selected by the warden. In some cases, the steganographic constraint does not result in ...

The increased resolution of Quad Full High Definition (QFHD) offers significantly enhanced visual experience. However, the corresponding huge data throughput of up to 530 Mpixels/s greatly challenges the design of real-time video decoder VLSI with the extensive requirement on both DRAM bandwidth and computational power. In this work, a lossless frame recompression technique and a partial MB reo...

Random access is a multiple access communication protocol where the users simultaneously communicate with a base station (BS) in an uncoordinated fashion. In this work, we consider the problem of multiuser detection in a random access bandwidth request context. We propose an enhanced random access scheme where the fixed/low-mobility machineto-machine (M2M) devices pre-equalize their random acce...

Abstract— This paper presents a high-throughput area-efficient decoder design for the irregular Quasi-Cyclic (QC) Low-Density Parity-Check (LDPC) codes. Two new techniques are proposed, including parallel layered decoding architecture (PLDA) and critical path splitting. PLDA enables parallel processing for all layers by establishing dedicated message passing paths among them. The decoder avoids...
