针对海洋环境复杂多变造成的海洋浮标监测信号难以完整接收的问题,提出一种基于FPGA的海洋浮标卫星通信基带信号生成方法。在EDA工具上完成了基带信号的设计和仿真,并在实验室设计的海洋浮标卫星通信接收机上进行验证,实现了海洋监测数据实时发送的功能。测试结果表明,该信号稳定可靠,具有一定的应用价值。
In order to solve the problem of incomplete reception of ocean buoys monitoring signal caused by the changing environment,a satellite communication baseband signal generating method of the ocean buoys based on FPGA is proposed.The design and simulation of the baseband signal is completed by EDA and the signal is verified by the designed ocean buoys satellite communication receiver.The real-time marine monitoring data transmission is also realized.The results show that the signal is stable and reliable,and has important value.
