Kami mencadangkan sistem radio-over-fiber (RoF) dengan modulasi outphasing 1-bit. Sistem RoF yang dicadangkan tidak memerlukan penukar digital-ke-analog yang haus kuasa dalam pusat akses dan melonggarkan kelajuan operasi transceiver optik untuk mengurangkan kos peranti. Kami memperkenalkan dua konfigurasi untuk membolehkan modulasi fasa luar 1-bit dalam sistem kami; konfigurasi isyarat bercampur dan semua digital. Dalam konfigurasi isyarat campuran, kesan ketidakpadanan harmonik dan fasa/amplitud pada nisbah kebocoran saluran (ACLR) bersebelahan telah dianalisis melalui simulasi, dan penghantaran jalur lebar dengan lebar jalur isyarat 400 MHz telah disahkan secara eksperimen, mematuhi 3rd Projek Perkongsian Penjanaan (3GPP) standard untuk jalur gelombang milimeter. Selain itu, penghantaran jalur lebar dengan lebar jalur isyarat 1 GHz juga telah disahkan secara eksperimen untuk melebihi 5G dan 6G. Konfigurasi semua-digital boleh dilaksanakan dalam aliran reka bentuk digital standard. Konfigurasi ini juga telah disahkan untuk mematuhi piawai 3GPP dengan memilih frekuensi perantaraan dan persampelan dengan betul untuk mengurangkan kesan harmonik terlipat dan hingar pengkuantitian. Akhir sekali, sistem RoF yang dicadangkan dengan kedua-dua konfigurasi telah ditunjukkan mempunyai kecekapan lebar jalur yang lebih tinggi berbanding dengan sistem lain yang mematuhi piawaian 3GPP untuk ACLR. Oleh itu, sistem RoF yang dicadangkan menyediakan penyelesaian wayarles dalam bangunan yang kos efektif untuk sistem rangkaian mudah alih 5G dan 6G.

Abstract: We propose a radio-over-fiber (RoF) system with 1-bit outphasing modulation. The proposed RoF system does not require a power-hungry digital-to-analog converter in access points and relaxes the operation speed of optical transceivers to reduce device cost. We introduce two configurations to enable 1-bit outphasing modulation in our system; mixed-signal and all-digital configurations. In the mixed-signal configuration, the effects of harmonics and phase/amplitude mismatch on the adjacent channel leakage ratio (ACLR) were analyzed through simulation, and wideband transmission with a signal bandwidth of 400 MHz was experimentally verified, complying with the 3rd Generation Partnership Project (3GPP) standard for millimeter-wave band. Moreover, wide-band transmission with a signal bandwidth of 1 GHz was also experimentally verified for beyond-5G and 6G. The all-digital configuration can be implemented in a standard digital design flow. This configuration was also verified to comply with the 3GPP standard by properly selecting the intermediate and sampling frequencies to mitigate the effects of folded harmonics and quantization noise. Finally, the proposed RoF system with both configurations has been shown to have a higher bandwidth efficiency compared with other systems complying with the 3GPP standard for the ACLR. Therefore, the proposed RoF system provides a cost-effective in-building wireless solution for 5G and 6G mobile network systems.
