1. A signal transmission method, comprising:
receiving, by a reflector, W excitation signals; and
reflecting, by the reflector, data and L reference signals to a receiver, wherein the L reference signals are respectively carried in L excitation signals in the W excitation signals, wherein
W and L are both integers greater than or equal to 1, and L is less than or equal to W, and wherein the L reference signals are carried in L time domain units, and each of the L time domain units carries one reference signal, and two reference signal symbols carried in two adjacent time domain units are opposite.
