Multiband Waveform Design for an Ultrasonic Indoor Positioning System

In the last years, indoor positioning systems have become an ubiquitous part of smart spaces. The use of coded ultrasonic indoor positioning systems leads to accurate position estimation at reduced cost as the low propagation speed of sound allows the use of analog-to-digital converters at low sampling frequencies. In these systems, coding schemes play a key role in the accuracy and robustness of ...
