Claim 10:
11. The electronic device according to claim 10, wherein
the electronic device is further configured to:
switch the receiving frequency among the candidate frequencies in a predetermined manner, to receive the frequency-selective header transmitted by the destination node, wherein
for each of the candidate frequencies, the receiving frequency is switched to the candidate frequency and remained for a target time period, and the target time period is twice of a time period of a single hop in the frequency-selective header;

calculate a correlation between a received wash sequence in a single-hop frame structure corresponding to a candidate frequency and a local wash sequence; and
determine a candidate frequency corresponding to a correlation which is greater than a predetermined value as the first optimal receiving frequency.
