摘　　要：考虑在提供通信服务时补偿租赁卫星资源的成本问题,主要任务是使频率和能量损失最小化,提出了一种基于自身信号相减的方法,即载波补偿。为了支持该模式,已经开发了用于实现“载波补偿”模式的模型和算法。在FPGA的基础上,创建了具有载波补偿模式的设备,并获得了硬件和软件测试的结果,同时确认了时间的减少以及结果信号搜索和减法的损失,最终的解决方案可以大大减少卫星通信信道的资源。Consideringthe cost of leasing satellite resources when providing communication services,the main task is to minimize frequency and energy loss.A method based on subtraction of its own signal is proposed,namely carrier compensation.To support this mode,models and algorithms are developed for implementing the“carrier compensation”mode.On the basis of FPGA,a device with carrier compensation mode is created,the test results of hardware and software obtained,and at the same time,the reduction of time and the loss of the resulting signal search and subtraction also confirmed.The final solution can greatly reduce the resources of the satellite communication channel.
