VCSEL-based differential modulation technique for high-speed gigabit passive optical networks

Performance of grey‐coded IQM‐based optical modulation formats on high‐speed long‐haul optical communication link

“…A lesser complex and cost‐efficient way is to use digital signal processing (DSP) techniques to compensate for these fibre impairments in the electrical domain. Recently, various research works have been reported by different research groups to enhance the system performance of optical modulation formats [3–15]. Mehra et al .…”
