AI Technical Summary

Benefits of technology

This patented technology allows signals from different parts of the network to share certain frequencies while still being transmitted effectively with minimal effort or extra processing on other devices connected thereto. It eliminates any unnecessary corrections that may have been added when needed. Additionally, this method uses detectors at both ends of communication channels to estimate how long they will take up transmission time based upon their distance between them. By calculating these estimates accurately, the device can adjust its own timing accordingly more efficiently. Overall, this new technique saves computational resources compared to traditional methods like repeating data over multiple connections.

Problems solved by technology

The problem addressed by this patented technique relates to accurately measuring the timing differences during data transmission over shared radio frequencies due to factors like delays caused by interference from other devices transmitting simultaneously with that bandwidth. This measurement helps determine if any issues such as synchronization failures may occur beforehand. However, current methods require extra resources beyond what would otherwise make them difficult to use without sacrifices accuracy.

Abstract

The embodiment of the invention discloses an LTE receiving channel delay correction method, a device and a base station with the device. The method comprises the steps of receiving uplink sounding signals of multiple users with multiple antennas; selecting a user from multiple users as a set user, and according to the uplink sounding signal of the set user acquiring the power delay spectrum of the set user in each receiving channel; according to the power delay spectrum of each receiving channel respectively acquiring the delay value of each receiving channel; and according to the delay value of each receiving channel respectively carrying out delay adjustment on each receiving channel. In this embodiment, the characteristic that the LTE system needs to employ the sounding signal of the user and a power delay spectrum estimation algorithm to compute the PDP estimation so as to obtain the power delay spectrum is employed, and then the delay adjustment value is obtained according to the power delay spectrum, thus the delay correction of the radio frequency receiving channel in the base station is realized.
