<p>The invention relates to a bandwidth and frequency offset estimation method, and in particular, to a bandwidth and frequency offset estimation method based on a spectrum shape. A bandwidth and frequency offset estimation method comprises: comparing sample values of an input signal with at least one threshold value; estimating a plurality of positive and/or negative frequencies corresponding to different threshold values; and determining a bandwidth and a frequency offset according to the plurality of positive and/or negative frequencies.</p> |
