E2-251: Communication Systems Design (Aug-Dec)

Course Description
  • This course gives a comprehensive treatment on how to design communication systems. Emphasis will be given to communication link design principles and communication transceiver design fundamanetals. The course will introduce and elaborate on transmit/receive architectures and subsystem requirements/specifications for modern communication systems. A key component in the course is the modeling of impairments in the transmit and receive chains. Algorithms for the compensation of these impairments using digital processing techniques in the baseband is another highlight in the course. The role of deep neural networks (DNNs) in communication systems design will be introduced. Design of visible light communication link using LEDs and photodiodes will also be covered. There will be Matlab exercises and assignments.
Course Content
  • Communication link design for AWGN channels; path loss models, noise figure, receiver sensitivity, pink noise, link budget for deep space communication - a case study.
  • Communication subsystem requirements/specifications and impairments modeling: analog front-end, up/down conversion architectures, oscillator phase noise, sampling jitter, IQ imbalance, carrier frequency offset (CFO), sampling frequency offset (SFO), error vector magnitude (EVM), DAC/ADC interface, quantization noise and clipping, dynamic range, ADC noise floor, non-linearities: 1 dB compression point, IIPn, power amplifier (PA) non-linearities, AM/AM, AM/PM.
  • Compensation techniques: Tx/Rx IQ imbalance estimation and compensation, effect of CFO in OFDM, CFO estimation and compensation in OFDM, SFO estimation and correction in OFDM.
