Abstract
Methods and apparatus for performing a ranging operation are provided. In one example, an apparatus comprises a transmitter circuit, a receiver circuit, a controller, and a code storage. The controller can obtain a first code from the code storage, determine, from the first code, first timing information and first amplitude information of a corresponding first group of one or more signals, and control the transmitter circuit to transmit the first group of one or more signals based on the first timing information and the first amplitude information. The controller can configure a matched filter based on the first timing information and the first amplitude information, identify return signals of the first group of one or more signals based on processing received signals using the configured matched filter, and perform a ranging operation based on the identified return signals and the first group of one or more signals.
