Sistem multicarrier ditapis universal (UFMC) menawarkan fleksibiliti menapis sub-jalur dengan lebar jalur sewenang-wenang untuk menyekat pelepasan luar jalur (OoB), sambil mengekalkan keortogonan antara sub-jalur dalam satu sub-jalur. Percanggahan pengayun antara pemancar dan penerima mendorong mengimbangi frekuensi pembawa (CFO) dalam sistem praktikal. Dalam makalah ini, kami mencadangkan kaedah anggaran CFO baru untuk sistem UFMC yang mempunyai kerumitan pengiraan yang sangat rendah dan kemudiannya boleh digunakan dalam sistem praktikal. Untuk mengeksploitasi sepenuhnya lebar jalur koheren saluran, simbol latihan direka bentuk untuk mempunyai beberapa segmen yang sama dalam domain frekuensi. Akibatnya, bahagian penting CFO boleh dianggarkan dengan hanya menentukan korelasi antara isyarat yang diterima dan simbol latihan. Hasil simulasi menunjukkan kaedah yang dicadangkan boleh mencapai prestasi yang hampir sama dengan kaedah sedia ada malah prestasi yang lebih baik dalam saluran yang mempunyai nilai parameter pereputan yang kecil. Kaedah yang dicadangkan juga boleh digunakan dalam sistem multicarrier lain, seperti pemultipleksan pembahagian frekuensi ortogon (OFDM).

Abstract: Universal filtered multicarrier (UFMC) systems offer a flexibility of filtering sub-bands with arbitrary bandwidth to suppress out-of-band (OoB) emission, while keeping the orthogonality between subcarriers in one sub-band. Oscillator discrepancies between the transmitter and receiver induce carrier frequency offset (CFO) in practical systems. In this paper, we propose a novel CFO estimation method for UFMC systems that has very low computational complexity and can then be used in practical systems. In order to fully exploit the coherence bandwidth of the channel, the training symbols are designed to have several identical segments in the frequency domain. As a result, the integral part of CFO can be estimated by simply determining the correlation between received signal and the training symbol. Simulation results show that the proposed method can achieve almost the same performance as an existing method and even a better performance in channels that have small decay parameter values. The proposed method can also be used in other multicarrier systems, such as orthogonal frequency division multiplexing (OFDM).
