Aims

At the end of this lecture, the students will be able to
- characterize the impairments associated with the sampling and quantization and an analogic signal,
- explain the form, and understand the equations corresponding baseband and passband digital transmission,
- explain the concept of matched filter, explain its interest in a receiver, and compute the associated perfomance,
- understand the methodology to compute the performance of a system as a function of Eb/NO, and apply this methodology to different systems,
- use the mathematical description associated with a bandpass linear modulation and compute the associated spectral efficiency
- provide a discrete time equivalent of an analog communications system (for simulation purposes),
- understand and apply the concept of forward error correction for block or convolutional codes,
- explain and motivate the use of hard and soft decoding,
- compute wave propagation in homogeneous non dispersive conductive and non conductive media
- compute reflection and transmission coefficients at planar interfaces
- identify the parameters of propagation modes in rectangular and parallel plate waveguides and understand the conditions leading to surface waves
- calculate the elementary radiation characteristics of simple antennas
- describe the components of satellite and horizontal transmission links
- compute the power budget and the signal to noise ratio of a herztian communication link
