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.
