摘      要：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.
