An impulse radio (IR) 60 GHz positioning system is proposed to provide accurate positioning. Two typical IR signals for positioning systems, namely polarity codes and pulse position modulation (PPM), are considered. The ranging and positioning accuracy and reliable distance in residential environments are investigated. Both line-of-sight (LOS) and non-line-of-sight (NLOS) channels are examined. Simulation...
Indoor localization techniques can produce significant errors in non-line-of-sight (NLOS) channels. To mitigate this problem, a new approach to channel identification based on the ratio of the minimum slope and skewness of the output of an energy detector is presented. The IEEE 802.15.3c 60 GHz channel models are used to examine the performance of this technique. The simplicity of the proposed approach...
