Scheme Improvement and Performance Analysis of Efficient Multi-Carrier Synchronization

In this paper, an improved generalized Frequency division multiplexing (GFDM) transmission synchronization scheme is proposed to achieve low latency and high reliability. By introducing coded generalized Frequency division multiplexing (CGFDM), optimizing loop prefix (CP) and subcarrier configurations, and reducing leading code length, the paper significantly reduces the peak-to-average power ratio (PAPR) while maintaining spectral efficiency. Through simulation experiments, the performance advantages of the proposed scheme under different SNR and frequency offset conditions are verified, especially in the aspects of time synchronization and frequency synchronization, and its potential in the application scenarios such as coaxial cable transmission with high latency and reliability requirements is demonstrated.
