Problems solved by technology

However, none of the previously studied power amplifier behavior models can be used to represent the power amplifier behavior model in a multi-beam transmitter system, so it is necessary to remodel the power amplifier behavior model in a multi-beam transmitter system to establish a model that can simulate the nonlinearity and memory of the power amplifier. effects, and multibeam PA behavior for linear and nonlinear crosstalk for efficient compensation

Description

technical field [0001] The invention relates to the technical field of power amplifier behavior analysis, in particular to an equivalent circuit, an analysis method and a system of a dual-beam power amplifier behavior model. Background technique [0002] The air-space-ground-sea integrated information network is based on the space-based network and the ground network, which can support land, sea, air, and space users to access and provide on-demand services. As a national information infrastructure with strategic significance, the air-space-ground-sea integrated information network plays an important role in safeguarding national interests and promoting economic development. [0003] As an important part of building a global seamless network integrating air, space, ground and sea, low-orbit satellite communication needs to have the ability to transmit data at a high rate. Due to the limited spectrum resources of satellite communication, traditional satellite communication t...
