Anggaran mengimbangi kekerapan ialah teknik penting dalam reka bentuk penerima komunikasi tanpa wayar. Dalam banyak aplikasi, nada frekuensi tunggal sampel dipilih sebagai simbol/jujukan latihan untuk penyegerakan frekuensi. Di bawah andaian ini, anggaran offset frekuensi boleh dianggap sebagai masalah anggaran offset frekuensi pembawa tunggal. Dalam Surat ini, penganggar kekerapan kemungkinan maksimum maksimum dicadangkan. Penganggar ini cekap pada SNR sederhana dan tinggi. Berbanding dengan penganggar lain, penganggar yang dicadangkan kurang sensitif terhadap ambang varians dan menawarkan tahap kerumitan pengiraan yang boleh dilaksanakan. Penganggar yang dicadangkan sesuai untuk kes offset frekuensi tinggi dan aplikasi penyegerakan frekuensi kasar/halus.

Abstract: Frequency offset estimation is an important technique in receiver design of wireless communications. In many applications, sampled single frequency tone is selected as training symbol/sequence for frequency synchronization. Under this assumption, frequency offset estimation can be regarded as the problem of single carrier frequency offset estimation. In this Letter, an approximate maximum likelihood frequency estimator is proposed. This estimator is efficient at moderate and high SNR's. Compared with other estimators, the proposed estimator is less sensitive to the variance threshold and offers feasible levels of computation complexity. The proposed estimator is suitable for high frequency offset cases and coarse/fine frequency synchronization applications.
