摘要：Communication methods and communication devices are disclosed. The

communication method, performed by a communication device, including: receiving atime-domain OFDM symbol; converting the time-domain OFDM symbol to a frequency-domain OFDM symbol containing a plurality of pilot sub-carrier received signals;extracting the plurality of pilot sub-carrier received signals from the frequency-domainOFDM symbol; estimating a plurality of first frequency-domain channel averageresponses (CARs) of pilot sub-carriers according to the plurality of pilot sub-carrierreceived signals and a plurality of pilot sub-carrier transmitted signals; determining apilot sub-carrier number parameter for a sub-carrier block according to a statisticalinformation of channel delay; splitting all sub-carriers into a plurality of sub-carrierblocks according to the pilot sub-carrier number parameter; and estimating secondfrequency-domain CARs of all sub-carriers by performing weighting average andinterpolation based on the first frequency-domain CARs of the pilot sub-carriers in allsub-carrier blocks.
