A technique to choose nodes to track jammers by estimating signal-to-noise Ratio (SNR), jammer-to-noise ratio (JNR), and jammer received signal strength (JRSS) are introduced in this paper. We proposed a boundary node selection threshold (BNST) algorithm. Every node can become a boundary ...
We introduce an estimator of the signal-to-noise ratio (SNR) of the system by means of time averages of running complexity measures such as Shannon and Rényi entropies, and prove its asymptotical equivalence with the linear SNR in the case of Shannon entropies of symbol distributions. A ...

Estimates the signal-to-noise ratio (SNR) given a set of manual annotations (in seconds). This algorithm estimates the signal-to-noise ratio in recordings that contains manually annotations of the desired and noise segments. The assumption that the noise is completely uncorrelated from the desired...
aA method for estimating the spreading sequence of a DS-SS signal in a non-cooperative context has been proposed. The method provides good results even for very low signal to noise ratio (negative SNR). No hypothesis was done on the nature of the spreadingsequence: it can be a sequence ...
