Abstract: The method disclosed herein is implemented in a radio receiver to detect an AWGN channel, where the radio receiver comprises a rake receiver. The radio receiver receives signals transmitted via a propagation channel from a transmitter, and determines that the propagation channel is an AWGN channel when a filtered version of a minimum value of a metric is lower than a threshold value. The metric relates to a difference between a normalized measured power profile of the propagation channel and a normalized power template, which normalized power template is dependent on predetermined sampling timing shifts and on rake finger positions within the rake receiver.

Abstract: There is described a DC-DC converter having a Step-Up stage (10) supplying a Step-Down stage (20). A common Step-Down controller is designed and configured such that a single reference voltage (VREF) is compared to the output voltage (VOUT_SD) of the Step-Down stage by a single comparator (61), producing a single error signal (VERROR). The error signal is then compared by comparators (62) and (63) to the two different saw signals (SAW1) and (SAW2) respectively in order to generate first and second pulse-width modulated signals (PWM_SU) and (PWW_SD) respectively that are inputted a the control unit (65) of the controller which, in turn, generates a first pair of control signals (1,2) and a second pair of control signals (3,4), which control switching of the Step-Up stage (10) supplying a Step-Down stage (20).

Abstract: A conversion between two texture compression formats comprises calculations performed at index-level for reducing handling of values with color bit-length and an amount of calculations with color values. Format conversion can thus be performed in real time upon displaying an image using the compressed texture data, without significant slowing down of a display rate of the images. It may be implemented in particular for conversion from DXT1—to ETC1 compression format, and a non-flipped or flipped orientation of an ETC1—compressed texture data block can thus be determined from said texture data block as initially compressed in DXT1 format.

Abstract: A current-mode regulator relies on indirect current measurement to facilitate slope compensation used to stabilize the operation of a buck converter. The current-mode regulator comprises an inductor, a switching network, and a controller. The inductor delivers an output current to a load. The switching network selectively connects the inductor input to an input voltage or a second voltage. The regulator controls the switching network. An inner loop control circuit of the regulator comprises the switching network, a current measuring circuit, a slope circuit, a comparator, and a switching controller. The current measuring circuit comprises a passive network connected to the inductor input and operative to indicate an inductor current as a measurement voltage. The slope circuit applies a time-varying voltage having a positive slope to the measurement voltage. The comparator compares a slope compensated measurement voltage to the control voltage. The switching regulator controls the switching network in response to the output of the comparator.
