Abstract
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.
