Qu Baoping, Jing Zhan-rong, Chen Weijun · 2011
For passive location of the CDMA pilot signal, the paper establishes TDL channel model about multi-path transmission, and get the best test statistics based on Neyman-Pearson criteria and white gauss noise. According to the characteristics of pilot signal and by the use of mathematical tools it was simplified. And the paper establishes the best system based on related theory. When using signal to noise ratio as variable, we gain analytical expression for the probability of detection and the probability of false alarm of the receiver, and simulate the detection performance of system. Simulation shows that the channel model has a ideal performance of detection when the received SNR is over 20dB.
