摘要

研究了60 GHz脉冲无线电(IR)系统的测距定位精度。分析了加性高斯白噪声(AWGN)信道上相应的cram - rao下界(CRLB)。对可能影响精度的信号参数进行了分析。给出了在AWGN和室内住宅信道上的性能结果。其中，采用IEEE 802.15.3c任务组推荐的室内住宅信道模型。理论和仿真结果表明，即使在低信噪比(SNR)为5 dB的住宅视距(LOS)环境下，红外60 GHz系统也能达到毫米级精度。对于具有相同信噪比的住宅非视距(NLOS)环境，可以获得厘米级精度。

Accuracy analysis of an impulse radio 60 GHz positioning system

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.
