WebJul 17, 2024 · Specifically, exploiting the preamble signals with synchronization offsets, two ELMs are incorporated into a traditional MIMO-OFDM system to estimate both the residual symbol timing offset (RSTO) and the residual carrier frequency offset (RCFO). WebMay 25, 2024 · Abstract. A novel symbol timing synchronization algorithm by iterative method is proposed for FBMC / OQAM systems. In the iterative process, different methods are used for rough timing synchronization and fine timing synchronization. Firstly, the ZC (Zadoff-Chu) sequence delay correlation is used to estimate the coarse timing by …
