A 0.1–5GHz flexible software-defined radio (SDR) receiver is presented with three RF front-end paths (Main/Sub/HR paths). Main path and sub path can reject out-of-band blockers and harmonic interferences, and feature low NF and high linearity, respectively. Harmonic rejection (HR) path can effectively reject the harmonic interferences with simple calibration mechanism. Dual feedback LNA, class-AB...
Smart Mobile device are becoming popular platforms for information accessing, especially when coupled with recommendation system technologies. They are also treated as key tools for mobile users both for leisure and business applications. Recommendation techniques can increase the usability of mobile systems by providing more personalized and interested content. In this paper, a novel personalized...
This letter derives a computationally efficient sequential Monte Carlo solution for blind detection of direct-sequence code-division multiple-access systems over multipath fading channels by decomposing the observed data into a number of signal components. Then the parameters of each component can be estimated by the sequential importance sampling and Kalman filtering. In comparison with other similar...
