摘要：
The parametric model of the actual multi-path channel in frequency-do main was presented, the frequencydomain-basedcross-spectral super-resolution TDE algorithm(MUSIC) was proposed. The channel model of the OFDM systems in the frequency-domain was briefly introduced and the expression of the channel response was given with which the algorithm can be efficiently realized. The simulation results show the super-resolution capability of the algorithm and the ranging error is no more than 18 cm in the condition of SNR=0dB and BW=20MHz.
