| Abstract: | According to the characteristic of the reentry telemetry technology,the reentry telemetry system is required to have the ability to process real time signal and switch between the two modes.In this paper,FPGA is used to control the data access,PCI interface is selected in this system to communicate with the computer,and floating-point DSP is used to process the real time signal.The simulation result proves that this method is acceptable for the reentry telemetry real time signal processing system. |
