Noise Suppression Using Amplitude-Shaping OCDM With 16-Chip Multi-Level Phase-Shifted En/Decoder
We propose an amplitude-shaping (AS) technique to shape an en/decoded signal in 10-Gb/s coherent time-spreading optical-code division multiplexing (OCDM) with ON– OFF keying modulation format, using 16-chip multi-level phase-shifted keying en/decoders. By employing this technique, the pri...

| description | We propose an amplitude-shaping (AS) technique to shape an en/decoded signal in 10-Gb/s coherent time-spreading optical-code division multiplexing (OCDM) with ON– OFF keying modulation format, using 16-chip multi-level phase-shifted keying en/decoders. By employing this technique, the primary beat noise and the multiple access interference can be suppressed, and the code detection performance is improved. The bit error rate and the power penalty of the <inline-formula> <tex-math notation="LaTeX">$8\times 10$ </tex-math></inline-formula> Gb/s AS-OCDM, obtained from the calculation and the simulation, are improved, in comparison with the conventional OCDM system. |
