QCA-based Hamming code circuit for nano communication network

ABSTRACT Quantum-dot cellular automata (QCA) is one of the most promising technologies for designing digital circuits with high integration, ultra-low energy consumption, and high switching speed. The efficient implementation based on QCA has been verified in some nanocommunication code circuits. In this manuscript, a bottom-up method is adopted to design and implement novel 3-8 and 4-16 decoders. Based on the proposed structure, (7,4) and (15,11) Hamming codec circuits are implemented. The general design method of QCA Hamming code communication network is also given. For different generator matrices in Hamming codes, the proposed design only needs to modify the corresponding interconnection lines in the communication network without major adjustments to the circuit structure to achieve the same function. Compared with the Hamming code related designs in other studies, the proposed design has better hardware complexity. The proposed Hamming code circuit has a great performance improvement in terms of cell number, area, and clock delay. The above designs have been functionally verified by the QCADesigner.
