To reduce the navigation control cost, this paper proposes a mechanical guidance scheme that uses cam-link mechanism as steering for an automated guided vehicle with fixed driving path. According to principle, mathematical model of system and trajectory are established. By setting boundary conditions, is modeled using quintic polynomial. The contour directional cam obtained based on equation tr...

The perturbation-based nonlinearity compensation (NLC) method is considered in conjunction with a forward error correction (FEC) code that capable of detecting block errors. FEC decoding performed prior to the NLC, and NLC then only for blocks, could not be decoded correctly. total complexity thus dramatically reduced down 1% some cases w.r.t. standard, hard decision-directed decoding. Negligib...

Abstract This paper proposes a motion compensation algorithm based on PGA. Our first uses the PGA to estimate roughly phase error of SAR data, which is then exploited through several iterations compensate for and range migration caused by obtain focused image. A single iteration not only improves image quality, but also accuracy in next iteration. The simulation measured data show that can effe...
