摘要：The present disclosure provides example channel parameter estimationmethods and related apparatuses. In one example method, a cable modem (CM) obtains
a second data frame through a downlink channel between the CM and a cable modemtermination system (CMTS). The second data frame is generated after a first data framesent by the CMTS is modulated through the downlink channel, a zero-bit-loaded symbolof the first data frame includes no valid codeword, but includes a zero-bit-loaded NCPand an idle codeword identified by the zero-bit-loaded NCP, and the idle codewordincludes a data sequence used for channel parameter estimation. The CM can estimate achannel parameter of the downlink channel based on a data sequence in an obtainedzero-bit-loaded symbol of the second data frame and the data sequence in the zero-bit-loaded symbol of the first data frame.
