Abstract: A method for predictive level-crossing, LC, in an analog-to-digital converter, ADC, is provided. The method comprises the steps of comparing a first input signal sampled during a first sampling period with one of an upper threshold level and a lower threshold level to determine if a level crossing has occurred during said first sampling period. Which one of said two threshold levels that is compared with said first input signal is based on if a level crossing occurred during a prior sampling period directly prior to the first sampling period, and which one of the two threshold levels was compared to a prior input signal sampled during said prior sampling period.

Abstract: Example embodiments relate to methods for distance determination. One embodiment includes a method for determining a distance between a first radio signal transceiver and a second radio signal transceiver. The method includes receiving a first set and a second set of measurement results. The first set is acquired by the first radio signal transceiver based on signals transmitted from the second radio signal transceiver and the second set is acquired by the second radio signal transceiver based on signals transmitted from the first radio signal transceiver. The first set is representable as including, for each of a plurality of frequencies, a measurement pair. The method also includes calculating, for each frequency of the plurality of frequencies, a preliminary estimate of a value proportional to a one-way frequency domain channel response. Additionally, the method includes determining a final estimate of the value proportional to the one-way frequency domain channel response.
