DOI: 10.1109/lpt.2023.3268272

Abstract: We propose and experimentally demonstrate a low- complexity constant modulus algorithm (CMA) based on FPGA for 4-channel wavelength-division-multiplexing passive optical network (WDM-PON) employing 4-level pulse amplitude modulation (PAM4). The FPGA processes the 4 wavelength channels… read more here.

DOI: 10.3390/app14041663

Abstract: Four-level pulse amplitude modulation (PAM4) can transmit more information in the same symbol interval, effectively improving the information transmission rate and frequency band utilization of visible light communication (VLC). This paper proposes a method for… read more here.
