Abstract

The invention discloses a data processing method, device, storage medium and processor for channel estimation. Wherein, the method includes: the receiver receives pilot symbols through at least two receive antennas, wherein the pilot symbols are sent by at least two layered transmit antennas in the transmitter; each receive antenna of the receiver is based on a pair of pilot symbols Each layered transmit antenna performs a channel response to obtain a first channel estimate value of each layered transmit antenna; the receiver determines the channel estimated interference value between at least two layered transmit antennas based on the first channel estimate value; the receiver The difference between the first channel estimation value and the channel estimation interference value is determined as a second channel estimation value obtained by correcting the first channel estimation value by the channel estimation interference value. The invention solves the technical problem that the system throughput is low because the channel estimation interference value cannot be eliminated.

Description

technical field [0001] The present invention relates to the field of data processing, and in particular, to a data processing method, device, storage medium and processor for channel estimation. Background technique [0002] At present, when performing frequency-domain code division multiplexing on pilot symbols, the channel estimation is inaccurate due to the existence of interference between layers, especially when the channel delay spread is large, or the inter-layer interference is larger when there is a receiving delay. In the prior art, since the inter-layer interference is not considered, the inter-layer interference still exists, resulting in the problem of low system throughput. [0003] Aiming at the above problem of low system throughput because the channel estimation interference value between layers cannot be eliminated, no effective solution has been proposed so far. SUMMARY OF THE INVENTION [0004] Embodiments of the present invention provide a data proces...
