Abstract: Systems, apparatuses and methods may provide for technology that establishes a point of intersection based on a rate of change in a logarithmic function and generates a first linear estimation of the logarithmic function, wherein the first linear estimation has the point of intersection as an upper bound. Additionally, a second linear estimation of the logarithmic function may be generated, wherein the second linear estimation has the point of intersection as a lower bound. In one example, linear estimations of an antilogarithmic function may be similarly generated based on the rate of change of the antilogarithmic function.

Abstract: A mobile communication device is provided that includes a receiver configured to receive a signal. The communication device further includes a calculation circuit configured to determine a cumulant value of an order higher than two of the received signal, to determine a function value of the determined cumulant value and to compare the determined function value with a predefined value. The communication device further includes a decoder configured to decode the received signal. The communication device further includes a target signal detector configured to activate the decoder based on the comparison of the function value with the predefined value.
