Abstract
Trapping set decoding for transmission frames is disclosed. In one aspect, a trapping set decoder includes a decoder that performs decoding operations on an encoded codeword in received data, and a detector coupled to the decoder for detecting the presence of any one of a group of possible trapping sets in the decoding operations on the encoded codeword. A selection processor is also included, coupled to the decoder, for providing a decoded codeword by selecting one trapping set of the group of possible trapping sets, the selected trapping set being present in the decoding operations of the codeword, and by using the selected trapping set to produce the decoded codeword.
