Summary (in Polish)
he course introduces fundamentals of digital communication systems, almost exclusively at the physical layer. Project will help students to know how to simulate several processes that take place in digital communication systems and to get hands on experience.
Signals and Spectra - review.Digital Communication Signal Processing - overview. Classification of signals. Spectral density, autocorrelation of energy and power signals. Random signals. Signal transmission through linear systems.
Signal Formatting and baseband modulation Textual data (codes). Formatting analog signals (sampling, quantization), sources of corruption. Source coding. Pulse code modulation, baseband modulation. Correlative coding.
Baseband demodulation/detectionSignals and noise, SNR. Vectorial representation of signals and noise. Detection of binary signals in Gaussian noise. Intersymbol interference. Equalization.
Bandpass modulation and demodulation/detectionDigital bandpass modulation techniques: PSK, FSK, ASK. Detection of signals in Gaussian noise, correlation receiver. Coherent/noncoherent detection. Error performance for binary systems. M-ary signaling and performance.
Communication link analysisThe concept of link budget. Received signal power and noise power. Link budget analysis. Noise figure, noise temperature, and system temperature.
Channel codingWaveform coding and structured sequences. Linear block codes, error-detecting and correcting capability. Convolutional codes, Trellis diagram, Viterbi code. Reed-Solomon codes.
Modulation and coding trade-offsShannon-Hartley capacity theorem. Bandwith-effciency plane.Modulation and coding trade-offs. Bandwith-efficient modulations.
Project problems are to give the students hands-on experience with the material taught in the classes. They are assigned to small groups of students (2 students). Project will help students to know how to simulate several processes that take place in digital communication systems.
