Multicarrier phase ranging (MCPR) technique has been widely used in radio navigation, telemetry, radar, and many other fields. In an MCPR system, unique range estimation can be obtained within only the so-called unambiguous distance (UD) because of p

The beat radio interferometry (BRI) is a novel ranging scheme that achieves high accuracy with low-cost devices. A major problem with BRI is the lack of an efficient range estimation method that is valid in general measurement configurations and acco

Owing to the ubiquity of cellular communication signals, positioning with the fifth generation (5G) signal has emerged as a promising solution in global navigation satellite system-denied areas. Unfortunately, although the widely employed antenna arr

Full-duplex (FD) communication provides new opportunities for improving the throughputs of networks. However, this condition means that the number of senders increases from one to two within a certain range. We have to arrange the two nodes to send f

An attractive and challenging problem in source localisation is to locate a target in three-dimensional (3D) space using a single station. To satisfy the observability requirements and achieve higher accuracy, the authors draw on the idea of the inve

The ubiquity, large bandwidth, and spatial diversity of the fifth generation (5G) cellular signal render it a promising candidate for accurate positioning in indoor environments where the global navigation satellite system (GNSS) signal is absent. In
