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.

量子点自动机（QCA）是设计具有高集成度，超低能耗和高开关速度的数字电路的最有前途的技术之一。在某些纳米通信代码电路中，已经验证了基于QCA的有效实现。在本手稿中，采用了一种自下而上的方法来设计和实现新颖的3-8和4-16解码器。基于提出的结构，实现了（7,4）和（15,11）汉明编解码器电路。给出了QCA汉明码通信网络的一般设计方法。对于汉明码中的不同发生器矩阵，所提出的设计仅需要修改通信网络中的相应互连线路，而无需为实现相同功能而对电路结构进行重大调整。与其他研究中与汉明代码相关的设计相比，所提出的设计具有更好的硬件复杂性。所提出的汉明码电路在单元数，面积和时钟延迟方面具有很大的性能改进。以上设计已通过QCADesigner的功能验证。
