Abstract
A method includes for a designated pilot symbol of at least one pilot symbol to be inserted into a data sequence, determining a first subcarrier and a second subcarrier adjacent to a position of the designated pilot symbol in a frequency domain; at least separately determining a first position and a second position on the first subcarrier and the second subcarrier; determining a first symbol and a second symbol, so that the first symbol is capable of neutralizing interference on the designated pilot symbol of data symbols in positions other than the first position within a predetermined range of the first subcarrier, and the second symbol is capable of neutralizing interference on the designated pilot symbol of data symbols in positions other than the second position within a predetermined range of the second subcarrier; and respectively inserting the first symbol and the second symbol in the first and second positions.
