A new clipped PIC detector for asynchronous upstream OCDMA-PON

Projected block‐wise PIC detection for communication systems with non‐negativity constraints

“…The SIC detection follows a serial approach in cancelling interference of different users [13]. The basic SIC detector is studied in the OCDMA environment in [14].…”

“…The PIC detection on the other hand cancels the interference of different users all at the same time [13]. The basic PIC detector is tested with prime codes in [18] and with 2D codes in [19] while the PIC detector combined with the hard limiter is proposed in [20].…”
