采用动态电源和数字预失真的高效多信道卫星通信的系统和方法
摘要：
本发明涉及采用动态电源和数字预失真的高效多信道卫星通信的系统和方法。一种无线电系统，其包括天线；基带模块，功率放大器；以及可变电源。基带模块被配置成向天线输出第一信号，基于计算的系数预失真第一信号，并输出第二信号。基于第一信号的一个或多个特性确定第二信号，以及如果在第一信号的一个或多个特性中存在变化，那么输出第二信号。功率放大器被通信地耦合到基带模块和天线，并被配置成放大预失真的信号。可变电源被通信地耦合到功率放大器和基带模块。可变电源被配置成接收第二信号并生成对应于第二信号的可变漏极电源电压。将漏极电源电压输出到功率放大器。
摘要（英）：

A radio system, comprising an antenna; a baseband module, a power amplifier; and a variable power supply. The baseband module is configured to output a first signal to the antenna, pre-distort the first signal based on computed coefficients, and output a second signal. The second signal is determined based on one or more characteristics of the first signal, and the second signal is output if there is a change in the one or more characteristics of the first signal. The power amplifier is communicatively coupled to the baseband module and the antenna, and is configured to amplify the pre-distorted signal. The variable power supply is communicatively coupled to the power amplifier and the baseband module. The variable power supply is configured to receive the second signal and generate a variable drain supply voltage corresponding to the second signal. The drain supply voltage is output to the power amplifier.
