These new codes are derived from modified prime codes and their cross-correlation is not larger than one.We also present a novel SAC-OCDMA system employing the new codes together with Mach–Zehnder interferometers to eliminate the multi-user interference (MUI). Compared with the systems employing modified quadratic congruence codes (MQC codes), numerical results verify that our proposed system can more effectively suppress the PIIN and eliminate MUI. Hence, the number of simultaneously users and total transmission rate increases significantly.application/pdf740300 bytesapplication/pdfzh-TWOptical code-division multiple access (OCDMA)spectral amplitude coding (SAC)modified prime codesmulti-user interference (MUI)Mach–Zehnder interferometerMach-Zehnder interferometer; Modified prime codes; Multi-user interference (MUI); Optical code-division multiple access (OCDMA); Spectral amplitude coding (SAC)Code division multiple access; Codes (symbols); Interferometers; Optical correlation; Optical systems; Signal encoding; Signal interference; Mach-Zehnder interferometer; Modified prime codes; Multi-use interference; Optical code division multiple access (OCDMA); Spectral amplitude coding (SAC); Total transmission rate; Optical communicationjournal articlehttp://ntur.lib.ntu.edu.tw/bitstream/246246/200611150121572/1/3458.pdf
