Claim 1:
2. The method according to claim 1, wherein the plurality of sequences comprise a first sequence corresponding to a first transmitted symbol and a second sequence corresponding to a second transmitted symbol, the first transmitted symbol and the second transmitted symbol are consecutive in time domain, and the first transmitted symbol is located before the second transmitted symbol; and
the performing a copy operation on the plurality of sequences comprises:
performing a first copy operation on the first sequence and the second sequence, so that both the first sequence and the second sequence have at least one same first complex-valued symbol, an end location of a first subsequence consisting of the at least one same first complex-valued symbol in the first sequence corresponds to a first reference point of the first transmitted symbol, and an end location of a second subsequence consisting of the at least one same first complex-valued symbol in the second sequence corresponds to a second reference point of the second transmitted symbol, wherein
the first reference point represents an end location of a transmitted symbol, and the second reference point represents a location from which a cyclic prefix is obtained through truncation in a transmitted symbol.
