... hashing schemes are studied [10]. Since our scheme is oriented to the preprocessing of the pairs of received vectors, the performance of the scheme for a blind attacker is also of interest for practical ... complexity of the implementation of our scheme that can be attained simultaneously make such a scheme attractive. In particular, we can recommend it for information transmiss...

... Therefore, for a specific UWB device, it can easily be obtained by k (k> 0) times distance measurements and range estimates in a pure LOS environment within the possible greatest distance, for ... circular traces can improve the performance of the hypothesis test using the variance to some extent. Therefore, we propose the combination of these two methods for NLOS identification and mi...
