WebDec 14, 2024 · It's statistical whether or not you get hit, and so we designed systems that can tolerate those bit flips. Host: Yeah. So, I mean just besides the human element, now we're talking about-- radiation, when it comes … WebA bit flipping check (BFC) algorithm is proposed to check and correct the errors of the compressed source block. The unreliable bits of each source block are selected by using the channel soft information to flip. If the reconstruction results of partial and all the source information are the same, the verification is successful.
