This paper first reviews covert timing channels with network packet frequencies as information carriers. Then, based on the study of communication and statistical models, it proposes a method to detect an enhanced covert timing channel and its use of carrier frequencies. With the help of MATLAB for simulation, several experiments have been conducted for the verification of the proposed method.
This paper presents an adaptive capability control technology to reduce training data in channel equalization, and designs a new space-time equalizer based on structure risk minimum criterion (SRM-STE). Simulation is carried out and the results are compared with a typical recursive least squares space-time equalizer (RLS-STE). It is concluded that SRM-STE has better tracking performance with much...
