Performance of different SAC-OCDMA detection schemes with NRZ and RZ data formats

Non-return-to-zero (NRZ) and return-to-zero (RZ) are two basic data formats in optical communication systems. In this paper, we compare the performance of NRZ against RZ with both AND as well as modified-AND subtraction detection techniques in spectral-amplitude coding optical code-division multiple-access (SAC-OCDMA) systems. Modified double-weight (MDW… CONTINUE READING
