Classical trust model for Peer to Peer networks calculates the global trust value by iteration of local trust value. Every transaction will cause iteration throughout the whole networks resulting in huge communication traffic and computational complexity. Collusion attack, sleeping attack, slander attack, and so on are also faced, which are caused by sparse transactions data and inaccurate computing...
In this paper, we propose a new look-up-table (LUT) based adaptive baseband predistorter which corrects signal distortions caused by the high power amplifier (HPA) and other analog processing modules in transmitters. For the fast initialization of the LUT, a corresponding initialization algorithm is proposed. An adaptive updating algorithm is also proposed to compensate for the time-varying property...
