Abstract
Embodiments of the present application provide a signal processing method and apparatus, and a device. The embodiments relate to an MU-MIMO system. The signal processing apparatus includes: a signal obtaining module and a sending module. A signal includes N spatial flows, and the signal includes a training field, where the training field includes a first part and a second part. Sub-carriers of an OFDM symbol in the second part of the training field are divided into N training sub-carrier sets TSSs in a division manner that is the same as a division manner of sub-carriers of an OFDM symbol in the first part of the training field, and each spatial flow corresponds to at least one sub-carrier in a TSS, in each frequency domain location, of each OFDM symbol in the second part of the training field. So that precision of the channel estimation is improved.
