Abstract
This application provides a signal transmission method and apparatus, a reflector, and a receiver. In one example method, a reflector receives W excitation signals, where W exciters may be configured to carry data and a reference signal that are reflected by the reflector; and the reflector reflects data and L reference signals to a receiver, where the L reference signals are respectively carried in L excitation signals in the W excitation signals, where W and L are both integers greater than or equal to 1, and L is less than or equal to W.
Claims11
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.
An apparatus, comprising:
- one or more processors;
- and
- a memory coupled to the one or more processors, wherein the memory stores instructions to be executed by the one or more processors, and wherein the instructions, when executed by the one or more processors, instructs the one or more processors to perform operations comprising:
- receiving W excitation signals;
- and
- reflecting 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, wherein the W excitation signals comprise T excitation signals, and the T excitation signals do not carry the reference signal and the T excitation signals do not carry the data, wherein T is an integer greater than 0.
A signal transmission method, comprising:
- receiving, by a receiver, a plurality of signals, wherein each signal comprises data and L reference signals, and the L reference signals are carried in L excitation signals, wherein the plurality of signals comprise a first signal and a second signal, and time domain units carrying the first signal and the second signal are adjacent;
- and
- demodulating, by the receiver, the plurality of signals, and wherein the demodulating, by the receiver, the plurality of signals comprises:
- performing, by the receiver, subtraction processing on the first signal and the second signal.
