Abstract
The ranging and positioning accuracy of an impulse radio (IR) 60 GHz system is investigated. The corresponding Cramér-Rao lower bound (CRLB) over an additive white Gaussian noise (AWGN) channel is analyzed. The signal parameters which may affect the accuracy are examined. Performance results over AWGN and indoor residential channels are presented. In particular, the indoor residential channel models recommended by the IEEE 802.15.3c task group are employed. The theoretical and simulation results obtained show that the IR 60 GHz system can achieve millimeter accuracy in residential line-of-sight (LOS) environments even with a low signal-to-noise ratio (SNR) of 5 dB. For a residential non-line-of-sight (NLOS) environment with the same SNR, centimeter accuracy can be obtained.
