| 摘要 |
The present invention relates to a method, apparatus, and computer program product, wherein frequency co-variances or correlations of a measured power delay profile or frequency correlation function are estimated at two different non-zero sub-carrier lags of an orthogonal frequency division multiplexing channel. A ratio of squared magnitudes of the two estimated frequency co-variances is calculated and a delay spread or coherence bandwidth of said channel is estimated based on the calculated ratio. |
