Abstract

Abstract

In this paper, based on localized subcarrier allocation in frequency domain and cyclic-shift allocation in time domain, a kind of ranging time and frequency structure for SC-FDMA system is designed, and adaptive detection thresholds computing method based on concept of peak-filtering to estimate interference and noise power is proposed for the detection of ranging signal. Theoretical analysis and simulation results show that, while ranging signals adopt different ranging code and different cyclic-shift, SINR requirements of 99% successful detection get reduce by 0.5~1 dB compared with traditional method adopting ensemble average correlation power, and the probabilities of false alarm get controlled in the meantime.
