Digital Signal Processing in Telecommunications

Lecturer:

Tutor:

Supervisor:

Department of Telecommunications Engineering

Synopsis:

This subject deals with principles and methods of digital signal processing starting with discretization and quantization of analog signals, digital signal processing using integral transformations (Z transformation , Fourier transformation, DFT, FFT, DCT, wavelets), digital filtering and adaptive filtering, low rate speech and image coding. Digital processing of two-dimensional signals is introduced. The accent is given on above mentioned methods and its realization in telecommunications equipment using of modern high-performance digital signal processors.
