Problems solved by technology

At the same time, analog communication is more sensitive to channel noise, so digital modulation is widely used in communication. The "Molecular Sensing and Computing Systems" proposed by Salehi et al. realizes the conversion of analog signals to digital signals. The conversion method can be regarded as Pulse Amplitude Modulation (PAM), but requires a more complex response

Abstract

The invention discloses a sine wave and pulse width modulation design method based on a chemical reaction network. A sine wave is obtained through a series of reaction formulae in the chemical reaction network, and can serve as a carrier wave of analog communication and a basis function of Fourier expansion. In addition, pulse width modulation is realized, so that digital-to-analog conversion anddigital communication under the chemical reaction network are realized.

Description

technical field [0001] The invention relates to the technical field of chemical reaction network information, in particular to a sine wave and pulse width modulation design method based on a chemical reaction network. Background technique [0002] Due to the continuous reduction of process size and the objective existence of quantum tunneling effect, the development of silicon-based computing has gradually reached a bottleneck. At this time, molecular computing is used as an alternative computing medium because of its good parallelism and extremely small size. . [0003] In 2013, Jiang Hua and others proposed "Digital Logic with Molecular Reactions", which realized digital logic gates based on CRNs and completed binary operations. However, as an important means of communication, analog communication is rarely implemented at the CRNs level. At the same time, analog communication is more sensitive to channel noise, so digital modulation is widely used in communication. The "...
