Cosmic radiation has several effects on the On-Board Processing(OBP)platform in satellite communications systems,and Single Event Upsets(SEUs)are one of its most important *** order to protect the Finite Impulse Response(FIR)filters against SEU,this paper proposes a novel Residue Number(RN)-based *** proposed method applies the transpose form of the FIR filter to avoid the fault missing caused by SEU on shift *** also adjusts the input intelligently to avoid the fault missing caused by SEU on the filter *** all the fault missing events are avoided,the modulus can be minimised to achieve the minimum *** analysis and simulation results show that the noise introduced by the input adjustment is *** injection shows that the fault missing rate of the proposed method is ***,FPGA implementation shows that the overhead of the proposed method is approximately 75% of Triple Modular Redundancy,and is only 1%-2% higher than that of the traditional RN-based design.

Modern satellite communication systems require on-board processing(OBP)for performance improvements,and SRAM-FPGAs are an attractive option for OBP ***,SRAM-FPGAs are sensitive to radiation effects,among which single event upsets(SEUs)are important as they can lead to data corruption and system *** paper studies the fault tolerance capability of a SRAM-FPGA implemented Viterbi decoder to SEUs on the user *** and fault injection experiments are conducted to verify that over 97%of the SEUs on user memory would not lead to output *** achieve a better reliability,selective protection schemes are then proposed to further improve the reliability of the decoder to SEUs on user memory with very small *** the results are obtained for a specific FPGA implementation,the developed reliability estimation model and the general conclusions still hold for other implementations.
