Objectives This course is oriented to future digital communications systems engineers.
Its aims are to identify and present inherent problems to real digital
communications systems and then to propose and study techniques to solve those problems,
covering advanced signal generation in the transmitter, channel modelling and its influence
over the transmitted signals and finally the required processing done at the receiver.
