Abstract: Empirical formulas are proposed for the superdirectivities of broadside linear and square arrays. The formulas are derived based on a large amount of numerical results of optimum directivity ...

In this short clip I’m testing out a hollow chisel mortiser on a piece of oak. You’ll see the bit plunge in and quickly carve a clean, deep mortise while the chips pile up. I’m still getting familiar ...
Abstract: We apply the innovations method to Viterbi decoding of convolutional codes. First, we calculate the covariance matrix of the innovation (i.e., the soft-decision input to the main decoder in ...
