Kami menyiasat pampasan penyebaran menggunakan gentian pemampasan penyebaran (DCF) untuk sistem komunikasi akses berbilang akses (CDMA) pembahagian kod cahaya pendek ultra pendek dalam persekitaran berbilang pengguna. Kami menggunakan pautan gentian yang terdiri daripada gentian mod tunggal standard (SMF) yang disambungkan dengan dua jenis DCF yang berbeza. Penyerakan gentian boleh dikurangkan dengan berkesan dengan melaraskan nisbah panjang DCF kepada SMF dengan sewajarnya. Beberapa kriteria untuk pampasan penyebaran dicadangkan dan prestasinya dibandingkan. Kami secara teorinya memperoleh kadar ralat sedikit (BER) sistem CDMA denyut cahaya ultrashort termasuk kesan serakan dan gangguan akses berbilang (MAI). Selain itu, kami mendedahkan hubungan bersama antara prestasi BER, penyebaran gentian, MAI, bilangan cip, lebar jalur isyarat dan jarak penghantaran buat kali pertama. Akibatnya, kami menunjukkan bahawa strategi pampasan kami meningkatkan prestasi sistem secara drastik.

Abstract: We investigate dispersion compensation using dispersion-compensating fibers (DCFs) for ultrashort light pulse code division multiple access (CDMA) communication systems in a multi-user environment. We employ fiber link that consists of a standard single-mode fiber (SMF) connected with two different types of DCFs. Fiber dispersion can be effectively decreased by adjusting the length ratios of DCFs to SMF appropriately. Some criteria for dispersion compensation are proposed and their performances are compared. We theoretically derive a bit error rate (BER) of ultrashort light pulse CDMA systems including the effects of the dispersion and multiple access interference (MAI). Moreover, we reveal the mutual relations among BER performance, fiber dispersion, MAI, the number of chips, a bandwidth of a signal, and a transmission distance for the first time. As a result, we show that our compensation strategy improves system performance drastically.
