Abstract

In this work we propose a frame architecture for asynchronous data transmission using ultrasonic OFDM pulses in reverberant environments. The frame has two different OFDM pulses modulated with BPSK. The first pulse plays an important role, it is used for time synchronization and to demodulated the unknown data in the second pulse by a differential demodulation scheme. The proposed frame architecture proved to be robust to the multipath in different scenarios. Results have demonstrated that it is possible to keep the bit error rate low in the presence of strong signal echos where other techniques fails, moreover, the simulations show that it would increase the reliability of ultrasonic indoor location systems.
