Abstract :
Wireless communications were clearly enhanced since 90´s thanks to Turbo Codes. The use of these codes in satellites and deep-space exploration could be ruined if radiation effects exceed their correction capability. SEU sensitivity of a Turbo Decoder intended for space applications has been analyzed in detail, injecting millions of faults by means of using an Autonomous Emulation System. Specifically, around 34.5 Mfaults per test in a sweep for four different parameters have been injected.
