Wireless distance measurement by means of ultra-wideband chaotic radio pulses

Abstract

A method for wireless distance measurement using ultrawideband chaotic radio pulses based on statistical analysis is proposed. Experimental results are discussed.

Measuring Received Signal Strength of UWB Chaotic Radio Pulses for Ranging and Positioning

“…A similar approach based on comparison of the envelope of a chaotic radio pulse with a threshold, to determine the power of the received signal, is described in [63]. However, these two methods have significant differences: in [63], the threshold value is determined by counting the number of pulses in a packet whose amplitude exceeds the threshold value, i.e., corresponding to the unit bit, and the number of pulses received with an error, i.e., recognized as a zero bit, and subsequent analysis of the number of data packets received with errors (PER, packet error ratio). The PER level is used as a criterion by which the radio pulse amplitude is determined.…”
