  • Motivation

  • MentorDSP specifications

  • Modulations

  • ComPRO

  • Validation

  • Future & Conclusion



Motivation

  • “Signal Processing has been the most boring course I ever had in my curricula” last year engineering student from X… institute

  • “I could not make the link between signal theory and engineering case studies” 5th year engineering student from X… institute

  • “Signal processing and modulation are a wonderful and an endless source of exam subjects”, teacher from X… institute

  • “It seems I synthetized a digital filter using Matlab ® but I have no idea what I really did and what it can be used for” student from Y… university

  • “Modulations? Yes I remember… O my god, so much theory” Engineer in mobile phone, two years after graduation

  • “I teach modulations with the white chalk, that’s the only way. Illustration is made in practical training. See my colleagues, I do not know exactly what they do in the training, if any…”, teacher from Z… engineering college



Motivation

  • Show signal processing at work

  • Illustrate the fundaments of common signal processing objects

  • Make the link with mobile phones

  • Give a tool to teachers for interactive learning

  • Focus the attention on concepts, steps, limitations

  • Capture the interest of students

  • Make signal processing attractive

  • Rise the interest for theory and how to apply it to real-case



MentorDSP Specifications

  • Two-years development in partnership with ni2designs, India

  • Around 50 Lab practical's covering basic signal processing concepts

  • Step-by-step description of concepts by problem-based approach



MentorDSP Specifications

  • Correspondence between time and frequency – (Casablanca Airport 10 March 09)



MentorDSP Specifications

  • Best-of: real-time spectrogram of the sound

  • Students discover the spectral contents of vowels, random signals, formants…



MentorDSP specifications

  • Signal generation: most basic signals, modulated signals, or signal based on analytical formulations



Modulations



Modulations

  • 3G-4G mobile phones use

    • Amplitude modulation
    • Phase modulation
    • Code Division Multiple Access
    • Numerical demodulation using digital signal processing
