Abstract


Ultra-wideband ( Ultra Wide -band UWB) communication technology using low duty cycle very narrow pulse transmission data with a high transfer rate , low power consumption , and ability to resist intercepted many of the advantages of UWB signal has a very wide bandwidth and extremely low power spectral density , the receiver received signal power close to or even below the noise power UWB signal is a low probability of intercept signals , subtle and strong . How to further improve the performance of ultra-wideband signal anti intercepted communications program in the military and civilian sectors have important uses , will become a hot research topic of communication in the modern non- cooperative communication reconnaissance . This article focuses on the ultra-wideband (UWB) communication anti intercepted depth study of the proposed anti-interception performance simulation program simulation and implementation, and analysis and comparison , and finally propose a new UWB anti intercepted communications program . This paper is summarized as follows : 1 , an overview of several conventional intercepted algorithms and techniques , made ??a theoretical analysis and simulation demonstration focused on secondary spectrum algorithm applied to UWB , the results are displayed according to the secondary spectral peak spectral line spacing can be effectively estimated its pseudo code cycle . Proposed a performance simulation program of the UWB anti intercepted , anti-interception performance of DS-UWB and TH-UWB simulation analysis , and carried out with the the DSSS system of anti-interception performance analysis , comparison , evaluation method to detect the signal-to-noise ratio for simulation the results showed that among the three at the same rate and RF bandwidth conditions DS-UWB has the best anti-interception performance . 3, the proposed one for a broader range of anti-interception performance evaluation method , as an evaluation method in order to detect the difference between the SNR, and a desired reception SNR - i.e. the relative SNR , and the simulation argument , analysis and experimental the results show that the method can be easily and vividly quantitative assessment LPI performance of each system . Introduced on the basis of the DS-UWB M-ary spread spectrum , proposed a new UWB anti intercepted communications program : M Yuan DS- UWB , through theoretical analysis and simulation , validation of the M-ary DS-UWB system than the DS -UWB has better anti-interception performance .
