AI Technical Summary

Technical Problem

In the existing technology, the terminal needs to calculate the Wiener filter coefficients in real time during the channel estimation process, which results in a large amount of calculation and high power consumption.

Method used

By dividing the channel state information into first channel state information and second channel state information according to their respective update cycles, and using the first cycle with a longer update cycle to calculate the initial Wiener filter coefficients, and then using the second cycle with a shorter update cycle to calculate the initial Wiener filter coefficients. These coefficients are used for filtering within the cycle to reduce the amount of real-time calculations.

Benefits of technology

This reduces the need for the terminal to calculate Wiener filter coefficients on each time slot, reduces the amount of calculation, and thereby reduces the power consumption of the terminal.

Abstract

The embodiment of the invention discloses a channel estimation result processing method and device, a terminal and a storage medium, and belongs to the technical field of communication. The method comprises the following steps: acquiring channel state information, wherein the channel state information comprises first channel state information and second channel state information; the updating period of the first channel state information is a first period, and the updating period of the second channel state information is a second period; the first period is greater than the second period; in the updating period of the second channel state information, acquiring an initial Wiener filter coefficient in the updating period of the second channel state information according to the first channel state information; according to the initial Wiener filtering coefficient and the second channel state information, acquiring a Wiener filtering coefficient in an updating period of the second channel state information; and filtering the channel estimation result according to the Wiener filter coefficient. According to the scheme, the real-time calculation amount of Wiener filter coefficient calculation is reduced, and the power consumption of the terminal is further reduced.
