A communication device and method include a reconfigurable receiver that is reconfigurable between communication, ranging and radar modes. The reconfigurable receiver includes a mixer configured to mix digital samples with a carrier phase estimate signal and configured to generate in-phase digital samples based on the carrier phase estimate. The reconfigurable receiver further includes a symbol correlator configured to correlate against the in-phase digital samples and generate correlated data, and a symbol binning unit configured to bin the correlated data and generate a first order channel impulse response estimate. The reconfigurable receiver yet further includes a multiplexer configured to switch the digital samples to the symbol binning unit when the reconfigurable receiver is configured in radar mode and to switch the correlated data to the symbol binning unit when the reconfigurable receiver is configured in a ranging mode.

Impulse-radio receiver and method

A processing module for a first lock device of a range determination system, the range determination system comprising a lock group comprising a plurality of lock devices of which the first lock device forms part, the plurality of lock devices physically spaced over a lockable element and configured to communicate with a key group comprising a plurality of key devices, a shortest distance between any one of the key devices of the key group and any one of the lock devices of the lock group providing for access to the lockable element relative to a threshold distance.

Processing module and associated method

A processing module for a receiver device is disclosed. The processing module is configured to provide for processing of a signal received by the receiver device from a transmitter device. The signal includes a secure training sequence divided into a plurality of time spaced blocks. The secure training sequence incoudes a non-repeating pattern of symbols. The processing module is configured to, based on a first phase marker in the first block and a second phase marker in the second block defining a phase difference of the signal between the first and second antennas and a known spacing of the first antenna relative to the second antenna, determine an angle of arrival of the signal relative to the receiver device.

The processor module comprises a channel estimate generation component arranged to output channel estimate information for a received signal, and a timestamping module arranged to determine a ToA measurement for a marker within a packet of the received signal based at least partly on the channel estimate information for the received signal generated by the channel estimate generation component. The channel estimate generation component comprises a validation component arranged to derive a validation pattern for the packet within the received signal for which a ToA measurement is to be determined, identify a section of the packet containing a validation sequence, and perform cross-correlation between at least a part of the validation sequence within the packet and at least a part of the generated validation pattern to generate channel estimate validation information.
