Subcarrier to subcarrier intermixing interference (SSII) is one of the bottlenecks in OFDM-PON system, which limits the transmission bandwidth and reduces the capacity.

SSII cancellation technique is a research hotspot, which is extensively study in journal, conference (OFC & ECOC), etc.

Previous works mainly focus on OFDM-PON downstream scenario, which essentially is a point-to-point (P2P) transmission scheme.

In this work, iteration interference cancellation method is used to mitigate SSII caused by square-law photo-detection in OFDM-PON upstream scheme.
