METHOD AND DEVICE FOR ESTIMATING THE LIKELIHOOD OF A MEASUREMENT ERROR IN DISTRIBUTED SENSOR SYSTEMS

摘要

The invention relates to a method for estimating, upon reception, the likelihood of a measurement error of a sensor k within a distributed network of sensors, which includes the following steps: initialising the estimate p_k[i = 0] and the weight of said estimate ^{Mk[i = 0]}; correcting the estimate by iteration according to the smooth information of the signal P^smooth_k [i] and the estimated reception value of the original measured signal x_o[i] calculating the estimate of the bit transmitted by the sensor k, x_k [i] (calculated according to the smooth information P^smooth_k[i]), the importance p_k[i] of the bit within the estimate(also calculated according to the smooth information P^smooth_k[i] and a parameter η) and the sum M_k [i] of the importance of all the bits considered up to the iteration i. The method is suitable for calculating a much more accurate estimate of the correlation.
