— This paper deals with the orthogonality factor, a transfer coefficient which allows the transformation of a transmitted orthogonal signal into a received Gaussian noise to be ...
Abstract— Recently the exact expression for the BER of rectangular QAM with arbitrary code mapping was obtained [1]. It is then natural to ask for the optimal constellation desig...
With the emergence of digital pen and paper interfaces, there is a need for gesture recognition tools for digital pen input. While there exists a variety of gesture recognition fr...
