Multi-carrier power adaptive control circuit module

Abstract

The invention discloses a multi-carrier power self-adaptive control circuit module. The r self-adaptive control circuit module is featured by simple and convenient control, high real timeliness, avoiding massive calculation and accurate and reliable measurement. The module is realized through the following technical solution that: a coupler C carries out real time sampling and coupling to the carrier powers on each carrier shunt and combined path; after being demodulated by a demodulator D, the carrier powers are sent to a monitoring processor; therefore, the carrier power values of each shunt and the combined path and the path loss information on each carrier link are obtained; the monitoring processor calculates according to each carrier power ratio input by a display screen and sends control information to an attenuator Att on each carrier shunt; and the attenuation value of the attenuator Att on each carrier shunt is adjusted self-adaptively. According to the module of the invention, each carrier power in a microwave channel is controlled precisely through demodulating and comparing the carrier powers of each shunt and the combined path in real time; and the problems of complex operation and relatively poor real timeliness in the prior art are solved.

Description

technical field [0001] The invention relates to a circuit module for adaptive control of multi-carrier power. Background technique [0002] The rapid development of microwave communication technology requires more and more capacity of the channel system. In order to save limited spectrum resources, improve the system capacity of microwave channels and support data transmission of various services, a microwave channel supports the transmission of multiple carriers. Has been widely used. However, the control of the power of multiple carriers in the microwave channel is a work that must be solved. The existing multi-carrier power control methods in microwave channels are mainly manual methods. That is, use a spectrum analyzer or a power meter to measure the actual output power of each carrier and the path loss on the carrier branch, and then calculate the attenuation value of the attenuator Att on each carrier branch after calculation according to the power ratio of each carr...

AI Technical Summary

Problems solved by technology

[0003] cumbersome operation

For each measurement, a spectrum analyzer or power meter is connected to each carrier branch to complete the measurement of the power of each carrier, and then calculate according to the power ratio of each carrier required by the system. There are many links involved in the control and the calculation is cumbersome.

[0004] Poor real-time performance

It is impossible to monitor the changes in the power of each carrier in real time, so that the power of each carrier cannot be monitored to achieve real-time adjustment of the power of each carrier

[0005] In terms of convenience and timeliness of operation, none of the existing methods can effectively accomplish the purpose of power adjustment of each carrier
