SIGNAL PROCESSING METHOD, APPARATUS AND DEVICE

摘要

Provided are a signal processing method, apparatus and device, which are applied to an MU-MIMO system. The signal processing apparatus includes: a signal acquisition module and a sending module. In the embodiments of the present invention, a signal is a signal containing N spatial streams. The signal contains a training field, wherein the training field includes a first part and a second part; sub-carriers of OFDM symbols of the second part of the training field are divided into N TSSs by adopting a division mode identical to that of sub-carriers of OFDM symbols of the first part of the training field; and each spatial stream has at least one corresponding sub-carrier in the TSS at each frequency domain position of the OFDM symbols of the second part of the training field. By means of a structure of the second part of the training field in the embodiments of the present invention, effective phase correction can be carried out on channel estimation obtained on other OFDM symbols of the first part of the training field, the accuracy of the channel estimation is further improved, and the estimation performance is improved.
