The relationship between positron mean lifetime and grain size, based on two statetrapping model, has been developed, and the saturation trapping at grain boundaries has been predicated.
A two stage belief-propagation(TSBP)decoding algorithm was developed based on trapping set state(TSS)detection to reduce the error floor of low-density parity-check(LDPC)codes.
