Abstract: Aspects of the preset disclosure are directed to processing an analog signal transmitted during active portions of a duty cycle. As may be implemented in accordance with one or more embodiments, an apparatus includes a high-speed sampling circuit that samples portions of such an analog signal at a first rate corresponding to the active portion of the duty cycle, and stores the sampled portions of the analog signal. A low-speed analog-to-digital converter accesses the stored sampled portions and converts the sampled portions to a digital form at a second rate that is slower than the first rate.

Abstract: A first-transceiver for use in an antenna diversity scheme. The first-transceiver comprises a first-time/clock-generation-unit; a first-receiver; and a first-transmitter. The first-receiver is configured to receive a wireless second-alignment-signal from a second-transceiver with a second-time/clock-generation-unit. The wireless second-alignment-signal is representative of a state of the second-time/clock-generation-unit. The first-transceiver is configured to set the first-time/clock-generation-unit, based on the wireless second-alignment-signal, to reduce an alignment-error between the first-time/clock-generation-unit and the second-time/clock-generation-unit. The first-transmitter is configured to transmit a wireless first-transmission-signal, in accordance with the first-time/clock-generation-unit, as part of the antenna diversity scheme. The first-transmission-signal corresponds to a second-transmission-signal that is transmitted by the second-transceiver. The antenna diversity scheme comprises aligned transmission of both the first-transmission-signal and the second-transmission-signal.

Abstract: A writing-block for writing data to a memory-buffer, wherein the memory-buffer comprises an ordered sequence of elements and the writing-block is configured to: receive an input-data-stream; and write the input-data-stream to the memory-buffer in a successive manner from a first-element of the ordered sequence to a predetermined-element of the ordered sequence. Following writing to the predetermined-element the writing-block is configured to continue to write the input-data-stream to the memory-buffer in a successive manner restarting at the first-element. In response to writing the predetermined-element, the writing-block is configured to also continue to write the input-data-stream to the memory-buffer in a successive manner from an element immediately following the predetermined element until a second predetermined-element of the memory-buffer.

Abstract: A first-transceiver system for use in an antenna diversity scheme. The first-transceiver system comprising: a first-receiver; a first-time/clock-generation-unit; a first-transmitter; and a timing-controller. The first-receiver is configured to receive a wireless first-common-signal from a third-party-transmitter, wherein the first-common-signal is representative of a common-signal transmitted by the third-party-transmitter. The timing-controller is configured to: receive signaling representative of the first-common-signal; receive signaling representative of a wireless second-common-signal as received at a second-transceiver, the wireless second-common-signal being representative of the common-signal; and generate a timing-signal based on the first-common-signal and the second-common-signal. The first-transceiver system is configured to set the first-time/clock-generation-unit, based on the timing-signal, to reduce an alignment-error between the first-time/clock-generation-unit and the second-time/clock-generation-unit. The first-transmitter is configured to transmit a wireless first-transmission-signal, in accordance with the first-time/clock-generation-unit, as part of the antenna diversity scheme that comprises aligned transmission of both the first-transmission-signal and a second-transmission-signal.

Abstract: Distance-based authentication is provided for mitigating undesirable interaction and/or attacks upon ranging systems, such as those involving vehicle entry or secure payment. As may be implemented in accordance with one or more embodiments, a leading edge of one or more pulses in a waveform of a signal is obscured as part of distance-based authentication. For instance, noise may be generated via a noise modulation circuit and combined with some or all of a leading edge of a pulse. Distance-based authentication is provided by transmitting a signal with a waveform having the obscured portion of the leading edge, which operates to mitigate detection of the polarity of the leading edge or otherwise of the leading edge itself.

Abstract: Aspects of the present disclosure provide communications between local and remote devices having low-frequency (LF) and high-frequency (HF) circuits. As may be implemented in accordance with one or more embodiments, the local device transmits an LF signal to the remote device, which synchronizes its clock based on the LF signal. Another LF signal is communicated from the local device to the remote device using a reduced quality factor, which can be implemented to facilitate synchronization. The clock is resynchronized based on the second LF signal and used to transmit an HF signal with a time delay. The local device synchronizes its clock based on the HF signal, and transmits another HF signal to the remote device using the clock and another time delay. The remote device re-synchronizes its clock based on the second HF signal while accounting for a trip time for communicating the first and/or second HF signals.
