Radiology for Surgeons in Clinical Practicescillation values. Finally, the simulation and experimental data are used to verify, the estimation method of the analog distortion parameters of the navigation signal and its influence on the ranging performance are given in detail.Retrieval 发表于 2025-3-30 13:12:04

Based on these mathematical preliminaries, we set up an optimization problem, which maximizes multiplexing efficiency under the constraint of constant envelope. The output of our method is a phase look-up table (LUT). Our method breaks the limitations in subcarriers, the numbCervical-Spine 发表于 2025-3-30 20:29:59
https://doi.org/10.1007/978-1-4614-0604-4a field test is conducted, where error position and velocity outputs of a commercial receiver and a target receiver onboard an UAV are under control. In addition, we successfully make the UAV land on the spoofing position by using the intelligent return function of the UAV. The results verify the coanimated 发表于 2025-3-30 21:59:36

A New Technique for Improving the Anti-jamming Performance of Vector Tracking Loop paper can be applied to arbitrary array without prior information of satellites’ directions and is not sensitive to the error of array. Copared to VTL based on EIG, VTL based on DR algorithm has lower complexity.ascend 发表于 2025-3-31 10:10:12
Generation Mechanisms and Experimental Verifications of Pseudo-range Biases for BDS Navigation Signa of Chinese Academy of Sciences to observe BDS signals. Pseudo-range biases of all visible BDS satellites are measured and evaluated with high accuracy thanks to the 40 m dish antenna and modern equipment of HRO. Finally, some important parameters for BDS receivers, such as the correlator spacing an逢迎春日 发表于 2025-3-31 15:37:57

A Cooperative Anti-spoofing Technology Based on Subspace Projectionthe spoofing signals not aligned with the authentic signals in the code domain. The two parts aim at different types of spoofing signals and spatial processing can also do help to data processing by eliminating the signals with larger power. At last, the proposed technology is verified by simulation誓言 发表于 2025-3-31 22:48:59
Design and Simulation of Synchronization Algorithm for Short Time Burst- Mode GMSK Signalsed algorithm provides an excellent performance against noise, delay spread, frequency offset and phase offset. The demodulator using this synchronization algorithm shows that the bit error’s performance degradation is only about 0.3 dB.
