PPP codes are derived from prime codes using a partitioning technique. The paper proposes the partitioned partial prime (PPP) code family for high‑rate SAC OCDMA PON applications. The design uses partial and padding schemes to reduce in‑phase cross‑correlation, and partition and two‑code keying schemes to mitigate phase‑induced intensity noise and shot noise. PPP codes exhibit good balance, flexible length, excellent orthogonality, and enable many simultaneous users with high‑rate transmission and low BER.
In this paper, a new code family named partitioned partial prime (PPP) code is proposed for high-rate spectral amplitude code (SAC) optical code-division multiple-access (OCDMA) passive optical networks (PONs) applications. They are derived from the well-known prime codes (PCs) and a manner of partitioning technique. To minimize in-phase cross-correlation (IPCC), we employ the partial and padding schemes. In addition, the influences of both phase-induced intensity noise (PIIN) and shot noise are further mitigated by the partition and two-code keying (TCK) schemes. The PPP code family has the property of good code balance, flexible code length, and excellent orthogonality. The numerical results show that the proposed system using PPP codes can substantially accommodate a lot of maximum and simultaneous users with high-rate transmission and low bit error rate (BER).
