摘要

在本文中，我们提出了一种频域的前导检测方案，这是迄今为止尚未尝试的基于OFDM的WLAN系统。阐述了在频域尝试前言检测方法的原因，分析了前言检测方法在频域未被尝试的原因。通过引入基于样本的FFT概念，我们提出了一种解决方案，即使在频域也能实现基于样本的操作。该算法在信噪比方面优于现有算法。

A Novel Frequency Domain Preamble Detection for OFDM based WLAN Systems

In this paper, we propose a preamble detection scheme in the frequency domain that has not been attempted until now for OFDM based WLAN systems. We explain the reason for trying the preamble detection method in the frequency domain and analyze the reason why the preamble detection method has never been tried in the frequency domain. By introducing the concept of sample-based FFT, we propose a solution to enable sample-based operation even in the frequency domain. The proposed algorithm shows improved performance in terms of SNR than the existing algorithm.
