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
