,General Conclusion and Future Prospeªcts,indoor scenes and complexity increase, the offline database will inevitably become large and the online retrieval time will also become long, which make visual indoor positioning unpractical. To solve this problem, we propose a Semantic and Content-Based Image Retrieval (SCBIR) method. By dividing t

Then, an EM based sparse Bayesian learning framework was built to capture the model parameters, i.e., the off-grid bias and the CFO. While in the learning process, a damped generalized a

Performance Analysis of SSK in AF Relay over Transmit Correlated Fading Channels,In this study, the error performance of a space shift keying (SSK) system with amplify-and-forward (AF) protocols on transmit correlated dual-hop channels over Rayleigh fading environments is analyzed, we obtain an average bit error rate (BER) expression in closed-form. The correctness of the analytical results is validated by simulations.

Research on Knowledge Mining Algorithm of Spacecraft Fault Diagnosis System,nd telemetry output under different conditions of spacecraft. Traditional expert system relies on static knowledge of experts to diagnose telemetry parameters. In order to solve the problem of rule-based expert system knowledge acquisition and less manual intervention, considering the characteristic
