The course covers how to mathematically model and analyze the components of radio communication and sensing systems such as a baseband modem, a DAC, an I/Q modulator, an upconversion mixer, an RF chain, a power amplifier, an antenna, a pre-select filter, a low-noise amplifier, an image reject filter, a down-conversion mixer, a channel-select filter, an ADC, an I/Q demodulator. It also covers the structure and difference between a digital baseband and digital IF transceivers. Digitally modulated signals and their power spectra are studied. Channel models and simulators are covered.

Undergraduate level: Calculus, Linear Algebra, Signals and Systems, Probability and Random Processes, Communications

Sorry about that in-phase baseband (IBB) and quadrature baseband (QBB) signals are mistakenly called in-phase and quadrature components in this recorded videos.
