Improved Label Design for Timing Synchronization in OFDM Systems against Multi-path Uncertainty
Chaojin Qing, Shuhai Tang, Na Yang +2
Timing synchronization (TS) is vital for orthogonal frequency division multiplexing (OFDM) systems, which makes the discrete Fourier transform (DFT) window start at the inter-symbo…

Metric Learning-Based Timing Synchronization by Using Lightweight Neural Network
Chaojin Qing, Na Yang, Shuhai Tang +3
Timing synchronization (TS) is one of the key tasks in orthogonal frequency division multiplexing (OFDM) systems. However, multi-path uncertainty corrupts the TS correctness, makin…

Cascaded ELM-based Joint Frame Synchronization and Channel Estimation over Rician Fading Channel with Hardware Imperfections
Chaojin Qing, Chuangui Rao, Shuhai Tang +2
Due to the interdependency of frame synchronization (FS) and channel estimation (CE), joint FS and CE (JFSCE) schemes are proposed to enhance their functionalities and therefore bo…
