Abstract: Cloud data transmission and scheduling process of private cloud platform and need to channel data transmission to achieve information communication, to private cloud platform in cloud data transmission channel of balanced design, improve the anti-interference ability of the cloud data transmission, reduce the error rate of data transmission. A data transmission channel equalization algorithm based on decision feedback equalization for private cloud platform is proposed. Were private cloud platform of cloud data structure interaction framework and the channel model construction, information fusion for cloud data transmission, matching detection method for data transmission of intersymbol interference suppression using adaptive interference, using decision feedback equalization crosstalk suppression, private cloud platform design for channel estimation and equalization, guarantee the convergence of private cloud platform cloud data transmission and channel modulation. Experimental analysis shows that the proposed method is used to transfer the cloud data of the private cloud platform, effectively removing the interference between the codes and the channel equalization, and reducing the error rate of the data transmission.
