Problems solved by technology

[0004] In the communication system, different carriers of carrier aggregation have unbalanced service load rate, and the unbalanced state changes rapidly with the management of radio resources. When the service load rate of the carrier changes greatly, the last calculation result of the pre-distortion coefficient does not match the current carrier service load rate, which will affect the effect of the pre-distortion

Embodiment Construction

[0066] The accompanying drawings of the present invention are only for illustrative purposes, and should not be construed as limiting the present invention. In order to better illustrate the following embodiments, some components in the drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, some known structures and their descriptions in the drawings may be omitted. understandable.

[0067] Such as figure 1 As shown, in one embodiment, a kind of predistortion processing method is provided, comprising the following steps:

[0068] S1. At the end of the current predistortion coefficient update cycle timing, obtain the current total service load rate change;

[0069] Specifically, the total service load rate is the ratio of the actual amount of data carried on the bandwidth corresponding to the total service load rate to the maximum amount of data carried. The total business load rate is obtained by cal...

Abstract

The invention relates to a pre-distortion processing method and device, a storage medium and equipment, and the method comprises the steps: obtaining current total business load rate variation when the timing of a current pre-distortion coefficient updating period is finished; determining a current actual pre-distortion coefficient according to a current total service load rate variable quantity;performing pre-distortion processing on a pre-distortion input signal in a next pre-distortion coefficient updating period according to a current actual pre-distortion coefficient, wherein the pre-distortion input signal is a signal after carrier aggregation. According to the method disclosed in the invention, the influence of the change of the total service load rate of the carrier on the pre-distortion stability can be effectively reduced, and a reasonable pre-distortion coefficient is provided to carry out pre-distortion processing on the signal after carrier aggregation.

Description

technical field [0001] The present invention relates to the technical field of carrier aggregation, and more specifically, to a pre-distortion processing method, device, storage medium and equipment. Background technique [0002] Carrier Aggregation (Carrier Aggregation, CA) is a technology that increases transmission bandwidth to meet the requirements of single user peak rate and system capacity improvement. CA technology can aggregate 2 to 5 LTE component carriers together to achieve a maximum transmission bandwidth of 100MHz, effectively improving the uplink and downlink transmission rates. [0003] The high-power transmitter used to transmit analog signals is the most power-consuming part of the entire communication system. The signal after carrier aggregation will be pre-distorted, and the pre-distorted signal will be input to the power amplifier in the transmitter for power amplification, and finally Input to the signal processing unit of the subsequent stage. The no...
