In this paper, we propose a hybrid time–frequency domain sign–sign joint decision multimodulus algorithm (Hybrid-SJDMMA) for mode-demultiplexing in a 6 × 6 mode division multiplexing (MDM) system with high-order QAM modulation. The equalization performance of Hybrid-SJDMMA was evaluated and compared with the frequency domain multimodulus algorithm (FD-MMA) and the hybrid time–frequency domain sign–sign...
Photonic generation of arbitrary waveform microwave pulse with tunable carrier frequency and phase based on tunable optoelectronic oscillator (TOEO) and a dual-drive Mach–Zehnder modulator (DDMZM) is proposed. Utilizing the frequency tunability of TOEO, the carrier frequency of the microwave signal can be tuned by adjusting the wavelength of the tunable laser source (TLS) and the tunable range can...
