  5. 29. Statistical Fault Detection with Applications to IMU Disturbances

    Författare :David Törnqvist; Fredrik Gustafsson; Alexander Medvedev; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fault detection; Linear systems; State-space models; Signal processing; State estimation; Fault observability; Inertial Measurement Unit; Automatic control; Reglerteknik;

    Sammanfattning : This thesis deals with the problem of detecting faults in an environment where the measurements are affected by additive noise. To do this, a residual sensitive to faults is derived and statistical methods are used to distinguish faults from noise. LÄS MER

  7. 30. Coherent Optical Transmission Systems : Performance and Coding Aspects

    Författare :Miu Yoong Leong; Sergei Popov; Gunnar Jacobsen; Enrico Forestieri; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Since the invention of fiber-optic systems in the 1970s, user demand has driven innovation forward, and each new generation of products has achieved higher data rates than its predecessor. Today, the most promising approach for further increasing data rates is coherent transmission with multi-level modulation and digital signal processing (DSP). LÄS MER
