The paper presents the theoretical derivation of an upper bound of the step size for the cm blind equalization algorithm. The analysis is performed under following assumptions, among other things: SISO (Single Input Single Output) channel model and whitening filtering before equalization procedure.

In the Air Traffic Control(ATC) communication system of Civil Aviation, the radio interference has become a big problem to the safety of the flight airplanes in recent yearsIn this paper, we propose an adaptive interference canceling technology to take radical measures to solve the problemWe separate the interference signals and the desired signals with the Constant Modulus(cm) algorithm, and then get the training signals on the assumption of that the signal is not the cm signal and the interference is cm signalThe study has very important practical value because our research work is doing around the difficulties disturbing civil air management department.

It is a laborious task for teachers to detect plagiarism in source codes produced by the students in programming classes. It is also difficult to distinguish between plagiarism and coincidental similarity in these source codes, since they are (1) often too short to extract enough algorithmic features and (2) obviously similar to. each other because they are produced for the same purpose. We propose a new method to measure similarity between source codes to detect source code plagiarism. Our method does not make pair-wise comparisons to find copied fragments among different students' works;rather, it compares the coding style of a newly submitted source code with a number Of source codes that have been produced by the same author. The coding style-a superficial feature appearing in source codes produced by the same author-is represented by a set of HMM-based stochastic models called "Coding Models" and utilized to make author identifications. We conducted an experiment and confirmed that the coding models could distinguish between source codes produced by different students, even if they were algorithmically quite similar to one another, thus indicating that our method can provide useful information for teachers to detect in-class source code plagiarism.
