An OFDM Bandwidth Estimation Scheme for Spectrum Monitoring

摘要：

An accurate bandwidth estimation scheme based on wavelet transform (WT) is proposed for OFDM, which estimates OFDM bandwidth using wavelet decomposition, signal reconstruction, moving covariance calculation and statistic histogram method in turn. Without requiring information about incoming signal and SNR level, the proposed scheme can estimate bandwidth parameter automatically and accurately even at low SNRs. Performance of the proposed scheme is shown by the theoretical arguments and simulations.
