Real-Time Digital Signal Processing for High-Speed Coherent Optical OFDM Synchronization

In high-speed coherent optical orthogonal frequency division multiplexing (CO-OFDM) systems, wide range estimation of carrier frequency offset (CFO) and hardware-efficient symbol timing synchronization are essential. The CFO estimation using the Chinese remainder theorem (CRT) was recently proposed...
