Claim 11:
12. A symbol processing method, comprising:
obtaining a plurality of complex-valued symbols;
dividing the plurality of complex-valued symbols into a plurality of sequences, wherein the plurality of sequences comprise a first sequence and a second sequence that are the same, the first sequence corresponds to a first transmitted symbol, the second sequence corresponds 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;
performing a cyclic shift on the first sequence and/or the second sequence, so that complex-valued symbols in a first subsequence in the first sequence are the same as complex-valued symbols in a second subsequence in the second sequence, wherein an end location of the first subsequence corresponds to a first reference point of the first transmitted symbol, and an end location of the second subsequence corresponds to a second reference point of the second transmitted symbol; and
transmitting the first and second transmitted symbols in the time domain, 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.
