Sažetak
The error floor performance of an LDPC code is related with the existence of certain substructures of the corresponding Tanner graph. Substructures that are called trapping sets, and especially absorbing sets as their subclass, determine the iterative decoding performance and are important contributors to the error floor for AWGN channel. The main subject of this talk are the absorbing sets in the Tanner graphs of LDPC codes constructed from the adjacency matrix of µ-geodetic graphs obtained from block designs.
