Positioning systems have become increasingly popular in the last decade for location-based
services, such as navigation, and asset tracking and management. As opposed to outdoor …

Complementary sets of sequences (CSS) and complete complementary codes (CCC) have
found numerous applications in wireless communications and radar sensing owing to their …

Golay sequences and complementary sets of sequences have been long studied for their
application in multisensor and communication systems. The feasibility of these systems …

This work analyses the effect of the receiver movement on the detection by pulse
compression of different families of codes characterizing the emissions of an Ultrasonic …

Many mobile robots and autonomous vehicles designed for outdoor operation have
incorporated ultrasonic sensors in their navigation systems, whose function is mainly to …

The Golay complementary sequences are widely used to detect digital signals immersed in
noise. The previous works have dealt not only with the application of sequences but also …

Complementary sequences are being employed to improve the results obtained in many
sensorial systems where it is necessary to enhance the signal to noise ratio imposed by the …

This work presents the performance analysis of an Ultrasonic Local Positioning System
(ULPS). The system is composed of four beacons, forming a square structure in the ceiling of …

This work presents an intelligent system which allows the detection of obstacles on railways.
The sensory system is based on one barrier of infrared emitters and another of receivers …

We extend the paraunitary (PU) theory for complementary pairs to comple-mentary sets and
complete complementary codes (CCC) by proposing a new PU construction. A special, but …
