With the prevalence of the online to offline (O2O) commerce, the short-distance instant logistics service becomes increasingly popular in China, which is a new logistics model emerged recently and provides timely logistics for O2O local life service. Being different from traditional logistics, extra waiting time generates when order's pick-up location arrival time is early than its pick-up ready time,...
This paper addresses the estimation of forest heights and its underlying ground topography by applying dual-baseline SAR tomographic techniques to single-pass L-Band PolInSAR data. In this paper the feasibiliy of this special single-pass tomographic configuration is demontrated over boreal forests at the test site of Edson inAlberta, Canada. The estimated ground topography and tree top heights are...

In non-cooperative communication system, symbol rate is a crucial part of parameter estimation. The symbol rate estimation is deeply researched by the use of Continuous Wavelet transform(CWT). And a new multi-synchronous reference(MSR)approach is proposed to extract precise symbol rate of M-ary Phase Shift Keying (MPSK) signal. The value of MSR algorithm is focused on lower signal-to-noise rate (SNR)...
A data-aided iterative algorithm to estimate the nonlinearities of wireless emitters for specific emitter identification (SEI) is presented. To achieve robust estimation, inter symbol interference (ISI) is removed by iteratively estimating the channel coefficients and nonlinear transmit symbols to achieve asymptotically unbiased estimation. The complexity of the iteration procedure is further reduced...
This paper develops a simple and efficient position method based on relative signal-strength prediction, which can be got from an inversion propagation model in cellular networks. The inversion propagation model can predict the propagation loss between any two points along the virtual propagation path from the base-station to mobile-station, which precision has been presented in. So the user's location...
