In Global Navigation Satellite System (GNSS) positioning, gross errors seriously limit the validity of Kalman filtering and make final positioning solutions untrustworthy. Thus, detection correction have become indispensable parts filtering. Starting by defining an incremental Chi-square method recursive least squares, this paper extends definition to detect errors, explains its nature relation with currently adopted variables in model data spaces, compares them predictive residual...
In order to better evaluate the relationship between reciprocity and time delay of fiber receiving system in atmospheric turbulence channel, a time-domain signal generation mathematical model is proposed for first time. A numerical solution Johnson SB probability density distribution (PDF) creatively given evaluating both communication ends, which relates normalized fluctuation variance light intensity Greenwood frequency. An experiment then carried out verifying measuring reciprocity. It...
In this letter, by exploiting both the temporal correlation of active user and signal statistical information, we propose a compressed sensing based multi-user detection for uplink grant-free non-orthogonal multiple access where activity varies dynamically in one frame consisting time slots. proposed method, channel estimation data are implemented jointly efficient slot-wise generalized approximate message passing (GAMP) algorithm, (AUD) is (MP) GAMP MP exchanges information through turbo...
In this letter, an efficient multiuser detection (MUD) is proposed for the grant-free non-orthogonal multiple access in scenario with dynamic active users and unknown temporal-correlated channels. The MUD performs user slot detection, channel estimation, data simultaneously by iterative generalized approximate message passing (GAMP) (MP) over joint factor graph. Concretely, GAMP to decouple transmissions of different users, MP update activity information. Finally, computer simulations are...
Eikonal and Transport equation solver are basic tools in the seismic wave simulation inverse problem. In this paper, High order solution of them can be obtained. We firstly employ factorized methods to solve source singularity Secondly, adopt Lax-Friedrichs Hamiltonian construct iterative solution. Thirdly, base on WENO scheme get high approximation For GPU parallel implementation, we Jacobi iteration method which is more suitable for computing. also present optimization codes. Finally, give...
Compared with electromagnetic current transducer and electronic transducer, fiber optic (FOCT) represents the developing direction of which has a series advantages, such as wide bandwidth, good insulation performance, high measuring accuracy, so on. FOCT is one kind new-type precise sensor based on principle Faraday magneto-optical phase circling, its' complicated structure results in shot noise, intensity hot interference have great effect FOCT's performance. Relativity noise random process...
