The lead author (Abu Baker) of the paper entitled, "LDPC Decoder: A Cognitive Radio Perspective for NeXt Generation (XG) Communication," which appeared in the 3rd quarter issue of the IEEE Circuits and Systems Magazine, admits to having plagiarized his work from "Energy/Power Estimation for LDPC Decoders in Software Radio Systems" authored by Chia-han Lee and Wayne Wolf of Princeton University, which appeared in the IEEE-SiPS 2005 conference and in order to obfuscate the plagiarism, he made minor modifications to the original work, which he thought would make it harder to trace the material back to the source. He also inappropriately plagiarized some paragraphs from another work by Professors Ian Akyildiz, Won-Yeol Lee, Mehmet Vuran and Shantidev Mohanty, entitled "NeXt generation/dynamic spectrum access/cognitive radio wireless networks: A survey," published in Computer Networks, Vol. 50, Issue 13, September 2006, Elsevier. He acknowledges that his co-authors, Soumik Ghosh, Ashok Kumar, and Magdy Bayoumi were totally unaware of any plagiarism. Throughout the process, the VLSI research team believed that Baker's write-up showed his own work.
