Application of CDMA Interference Estimation in Secure Transmission of Big Data in Blockchain Communication

In recent years, with the improvement of data transmission technology, blockchain has become one of the important ways of data transmission. When the blockchain data transmission traffic is large, the related encryption methods often cause data loss due to outdated technology and easy decoding, and are prone to leakage and loss of big data in transmission due to security vulnerabilities. Therefore, the application research of CDMA interference estimation in big data security transmission of blockchain communication is proposed. The security transmission scheme of blockchain communication big data is designed by using the subtractive multi-level iterative cancellation algorithm. On this basis, build a blockchain secure transmission channel to encrypt it, so that big data can be safely transmitted within the secure channel. The experimental results show that the proposed method can achieve the safe transmission of big data in the same blockchain environment, and has excellent operational efficiency and good performance. According to the above experimental results, after the application of the proposed method, the data can be detected and corrected while encrypting the blockchain communication big data to ensure the integrity of the data and realize the safe transmission of data.
