A method was published in 2020 for the estimation of the residual carrier frequency offset (RCFO) and sampling frequency offset (SFO) in WLAN OFDM systems. The purpose of this paper is to compare this method with one existing method for more examples to make a fair comparison in terms of estimation accuracy and computational load.

OFDM WLAN 系统中载波和采样频率偏移估计方法的性能

2020 年发布了一种用于估计 WLAN OFDM 系统中残余载波频率偏移 (RCFO) 和采样频率偏移 (SFO) 的方法。本文的目的是通过更多的例子将该方法与现有的一种方法进行比较，以便在估计精度和计算量方面做出公平的比较。
