Signal processing method, transmitting end device, and receiving end device

Abstract

Provided are a signal processing method, a transmitting end device, and a receiving end device. The method comprises: performing modulation processing on a first signal on the basis of a first signal modulation mode and a second signal modulation mode, to obtain a second signal, wherein the first signal modulation mode comprises OFDM, and the second signal modulation mode comprises a signal modulation mode other than OFDM. The present application provides two different signal modulation modes, i.e., the second signal modulation mode (e.g., the signal modulation mode other than OFDM) and the first signal modulation mode (e.g., OFDM), which are sequentially used for performing modulation processing on the first signal to obtain the second signal. Therefore, the advantages of modulation modes other than OFDM are fully utilized, and signal transmission performance is improved. Moreover, it is possible to implement the second signal modulation mode in a MIMO system by means of OFDM-related processing.
