论文摘要

在低信噪比(SNR)下,正交频段多路复用(OFDM)信号符号率受到限制。现有的载体编号估计算法缺乏足够的方法来处理低SNR。本文通过关联信号并应用快速傅立叶变换(FFT)操作,提出了一种在低SNR下具有低错误率的算法。通过改善现有算法,我们可以提高OFDM载体数量算法的性能。 OFDM有用的符号时间估计算法的性能通过估计载体和符号率的数量来提高。

Under a low Signal-to-Noise Ratio (SNR), the Orthogonal Frequency-Division Multiplexing (OFDM) signal symbol rate is limited. Existing carrier number estimation algorithms lack adequate methods to deal with low SNR. This paper proposes an algorithm with a low error rate under low SNR by correlating the signal and applying a Fast Fourier Transform (FFT) operation. By improving existing algorithms, we improve the performance of the OFDM carrier count algorithm. The performance of the OFDM's useful symbol time estimation algorithm is improved by estimating the number of carriers and symbol rate.
