WebMDS matrices are derived from MDS codes. An [n, k, d] code C is MDS if it meets the singleton bound d = n − k + 1. MDS matrices have the maximum differential and linear branch number (k + 1 for k × k MDS matrices) [15]. Some important properties of MDS matrices can be given as follows: i. A k × k matrix M is MDS if and only if every square … WebCurrent bias compensation methods for distributed localization consider the time difference of arrival (TDOA) and frequency difference of arrival (FDOA) measurements noise, but ignore the negative influence by the sensor location uncertainties on source localization accuracy. Therefore, a new bias compensation method for distributed localization is …

For example, for linear computations, i.e., matrix-matrix or matrix-vector multiplications, [5], [6] use Freivalds’ algorithm to detect Byzantine errors with high probability and exclude them in further processing. For polynomial computations, [7] uses properties of error-correcting codes to correct the erroneous results. Other dewalt 54v xr flexvolt wall chaser
