Inhalt:
Learning based on LabVIEW communications and NI USRP:
• Introduction to USRP including hardware blocks of Tx/Rx chains
• Getting familiar with LabVIEW communications environment and controlling VIs (Panel, diagram, etc.) and fundamentals of LabVIEW programming: data types, arrays, flow control (for/while loop), clusters, case structures, signal sources, sinks, signal processing tools, filters, time/ frequency domain analysis, etc.
• Transmission and reception of analog modulation schemes: AM/DSB-SC and FM
• Implementation of digital modulation schemes: ASK, FSK, BPSK, QPSK, 16-QAM, etc.
• Digital Tx/Rx: symbol mapping, upsampling/downsampling, pulse shaping (rectangular, Gaussian, RRC), matched filtering, pulse alignment, synchronization, and detection
• Phase synchronization, FDM and image rejection algorithm
• Eye diagram analysis: ISI, clock jitter, optimal sampling time, detection threshold
• Power control for over-the-air transmission in sub-6 GHz ISM bands and analysis on fading and multipath propagation effects
• Channel estimation, equalization (decision directed, linear LS, adaptive LMS), modelling: coherence bandwidth and propagation delay Learning based on MATLAB and USRPs (Communications toolbox and SDR support packages):
• OFDM Tx/Rx with frequency domain equalization (FDE) and synchronization (training sequence and frame detection)
• LTE downlink transmission (MIMO) including system information blocks (SIB) and spectrum analysis including estimation/calibration of carrier frequency offset (CFO)
• Impairments/distortion analysis: ACPR, EVM tool: IQ offset errors, phase noise, PA nonlinearity, etc. Learning based on GNU Radio and RTL-SDR:
• Introduction to GNU Radio with RF prototyping demonstration
• Spectrum analyzer implementation: RBW, VBW, sweep time, and phase noise
• Small Project/assignment for students
