1. A symbol processing method, comprising:
obtaining a plurality of complex-valued symbols;
dividing the plurality of complex-valued symbols into a plurality of sets, the plurality of sets comprise a first set corresponding to a first transmitted symbol and a second set corresponding to a second transmitted symbol, the first transmitted symbol and the second transmitted symbol are consecutive in a time domain, and the first transmitted symbol is located before the second transmitted symbol;
performing a copy operation on the first set and the second set, so that both the first set and the second set have first complex-valued symbols, a time domain index of a first subset start location of a first subset including the first complex-valued symbols in the first set is the same as a time domain index of a second subset start location of a second subset including the first complex-valued symbols in the second set; and
after the copy operation, performing signal processing on the first set and the second set, the signal processing comprising a cyclic shift or frequency domain weighting, and after the signal processing, the first subset start location corresponds to a location preceding a first reference point of the first transmitted symbol, a first subset end location of the first subset corresponds to a location following the first reference point of the first transmitted symbol, the second subset start location corresponds to a location preceding a second reference point of the second transmitted symbol and a second subset end location of the second subset corresponds to a location following the second reference point of the second transmitted symbol;
wherein the first reference point represents a transmitted symbol end location of a transmitted symbol and the second reference point represents a cyclic prefix location from which a cyclic prefix is obtained through truncation in a transmitted symbol.
