  • This paper proposes a method combining fractional Fourier transform (FRFT) and a high peak-to-average power ratiosuppression algorithm. Calculations show that as the order of the FRFT decreases, the peak-to-average power ratio of thesignal gradually decreases; combined with the suppression algorithm can further reduce the peak-to-average power ratio ofthe system and solve the problem of the suppression algorithm affecting system performance. At the same time, this paperuses the 2012 World Bank survey data of Chinese manufacturing enterprises to study the influence of financial repressionon the selection of financing channels of manufacturing enterprises. The research results show that financial repressionhas a significant impact on the choice of financing channels for manufacturing enterprises, which greatly increases theproportion of informal financial financing in the operating capital of enterprises and reduces the proportion of formalfinancial financing. Financial repression has led to an increase in the cost of formal financial financing, making enterpriseschoose informal financial channels for financing. Among them, large enterprises tend to choose commercial credit ininformal finance, while small and medium-sized enterprises choose private credit It is possible to choose two financingchannels, which reflects the ‘scale discrimination’ characteristics of financial repression.
