Abstract: In this paper we evaluate the probability of detection and the probability of false alarm for an OFDM pulse over AWGN channel. This type of pulse is useful for indoor location systems using ultrasounds due to the ability to accurately measure the time of flight by pulse detection while transmitting some data. Moreover, we can avoid the RF auxiliary channel by using an OFDM-based sync. The probability of OFDM pulse detection over white Gaussian noise will be presented as function of the probability of false alarm when a threshold technique is employed at the receiver. Furthermore, the pulse detection probability will be compared with a chirp pulse.
