VL - 3 IS - 0 SE - Articles DO - UR - https://ojs.imeti.org/index.php/PETI/article/view/229 SP - 1-3 AB - <p class="Context"><span lang="EN-US">The study proposes hybrid analog/digital transmission format scheme which integrated optical code-division multiple-access (OCDMA) and polarization multiplexing technique in free space optics (FSO) transmission. Orthogonal frequency division multiplexing (OFDM) transmits as the analog format and (on-off keying) OOK transmits as digital format in the study, respectively. In the proposed hybrid OCDMA system, it has high-speed transmission, signal security and low cost…etc. The <a name="OLE_LINK3"></a>multiple access interference (MAI) can be efficiently eliminated by using the balanced detection scheme at the receive end.</span></p> ER -
