Problems solved by technology

[0002] Communication systems generally use switching power supplies for power supply. When the communication system sends radio frequency signals, the load of the switching power supply is large. When the communication system receives radio frequency signals, the load of the switching power supply is small. In the actual communication process, due to the radio frequency of the communication system Signal transmission and reception are carried out alternately, resulting in the load of the switching power su...

Abstract

The invention discloses a ripple elimination device for a power supply of a communication system. The ripple elimination device comprises a control module and a virtual load module, wherein the control module is used for obtaining and recording the current communication power of a communication system, obtaining a current virtual load corresponding to the current communication power according to apreset power-load comparison table, generating a corresponding load control signal according to the current virtual load, and sending the load control signal to the virtual load module, and the virtual load module is used for adjusting the size of a virtual load according to the received load control signal so as to carry out load compensation on the power supply of the communication system according to the adjusted virtual load. By adopting the technical scheme of the invention, dynamic ripples of the power supply of the communication system can be eliminated, and the radio frequency signalquality and the data throughput are improved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a ripple elimination device for a power supply of a communication system. Background technique [0002] Communication systems generally use switching power supplies for power supply. When the communication system sends radio frequency signals, the load of the switching power supply is large. When the communication system receives radio frequency signals, the load of the switching power supply is small. In the actual communication process, due to the radio frequency of the communication system Signal transmission and reception are carried out alternately, resulting in the load of the switching power supply in a state of constant size change. In the process of dynamically adjusting the load, the following two problems are prone to occur: (1) The dynamic ripple is large, which affects the quality of the RF signal; (2) The dynamic response is not timely, which affects ...
