Dalam pautan atas Evolved UTRA (UMTS Terrestrial Radio Access), akses radio pembahagian frekuensi pembawa tunggal (SC-FDMA) telah diterima pakai kerana ciri nisbah kuasa puncak kepada purata rendah (PAPR) yang berfaedah, yang membawa kepada liputan luas peruntukan kawasan dengan kuasa penghantaran puncak terhad bagi peralatan pengguna. Kertas kerja ini mencadangkan penjanaan saluran perintis ortogon menggunakan gabungan FDMA dan CDMA dalam pautan atas Evolved UTRA berasaskan SC-FDMA. Dalam kaedah yang dicadangkan, kami menggunakan penghantaran FDMA teragih untuk pengguna mengakses serentak dengan lebar jalur penghantaran yang berbeza, dan menggunakan penghantaran CDMA untuk pengguna mengakses serentak dengan lebar jalur penghantaran yang sama. Selain itu, kami menggunakan jujukan kod dengan sifat korelasi auto yang baik seperti jujukan Korelasi Automatik Sifar Amplitud Malar (CAZAC) yang menggunakan anjakan kitaran untuk meningkatkan bilangan jujukan. Hasil simulasi menunjukkan bahawa purata prestasi kadar ralat paket menggunakan saluran perintis ortogonal dengan gabungan FDMA dan CDMA dalam persekitaran enam pengguna, iaitu empat pengguna setiap satu dengan lebar jalur penghantaran 1.25-MHz dan dua pengguna setiap satu dengan 5-MHz. lebar jalur penghantaran, menggunakan pengekodan turbo dengan kadar pengekodan sebanyak R = 1/2 dan modulasi data QPSK dan 16QAM bertepatan dengan baik dengan persekitaran pengguna tunggal dengan jalur lebar penghantaran yang sama. Kami menunjukkan bahawa struktur saluran perintis ortogonal yang dicadangkan menggunakan gabungan penghantaran FDMA dan CDMA yang diedarkan dan penggunaan jujukan CAZAC adalah berkesan dalam pautan atas Evolved UTRA berasaskan SC-FDMA.

Abstract: In the Evolved UTRA (UMTS Terrestrial Radio Access) uplink, single-carrier frequency division multiple access (SC-FDMA) radio access was adopted owing to its advantageous low peak-to-average power ratio (PAPR) feature, which leads to wide coverage area provisioning with limited peak transmission power of user equipments. This paper proposes orthogonal pilot channel generation using the combination of FDMA and CDMA in the SC-FDMA-based Evolved UTRA uplink. In the proposed method, we employ distributed FDMA transmission for simultaneous accessing users with different transmission bandwidths, and employ CDMA transmission for simultaneous accessing users with identical transmission bandwidth. Moreover, we apply a code sequence with a good auto-correlation property such as a Constant Amplitude Zero Auto-Correlation (CAZAC) sequence employing a cyclic shift to increase the number of sequences. Simulation results show that the average packet error rate performance using an orthogonal pilot channel with the combination of FDMA and CDMA in a six-user environment, i.e., four users each with a 1.25-MHz transmission bandwidth and two users each with a 5-MHz transmission bandwidth, employing turbo coding with the coding rate of R = 1/2 and QPSK and 16QAM data modulation coincides well with that in a single-user environment with the same transmission bandwidth. We show that the proposed orthogonal pilot channel structure using the combination of distributed FDMA and CDMA transmissions and the application of the CAZAC sequence is effective in the SC-FDMA-based Evolved UTRA uplink.
