Permutation algorithm Based on correlation coefficient matrix in Wireless Statistic Division Multiplexing
Wireless Statistic Division Multiplexing (WSDM) is a new channel multiplexing technology, compared to traditional multiple access, WSDM is much more agile, and can greatly improve the spectrum utilization of communication. However, there still exists permutation indeterminacy of separated signals as Independent component analysis, and the indeterminacy seriously affects the continuity between adjacent frames of separated signals in the processing course. Therefore, how to rightly adjust permutation of signals has a practical significance. In this paper, we introduce principle of WSDM, analysis the generated mechanism of indeterminacy, and propose a permutation algorithm, which is based on the correlation matrix between the observed signals and separated signals. The simulation results show that the algorithm can solve the problem of permutation indeterminacy, ensure the continuity between adjacent frames of separated signals, enhance the multiplexing effect of WSDM, and ensure the reliability of information transmission.
