Inhalt:

• Introduction

• Analogue-Digital Balance

• Software Defined Radio

• ADC/DAC Converter Performance Metrics and their evolution over time

• Signal Distortion mechanisms and metrics (IP3, EVM, ACPR, Spectral mask, wideband noise, reverse intermod)

• Impairment modelling

• System Complexity Analysis for Mixed Signal Systems

• Transceiver architectures, design and analysis

• Chained Noise figures and IP3 figures

• Dynamic Range in RX and TX, Automatic Gain Control in RX and power control in TX

• Synchronous versus asynchronous Architectures (RF DAC, PLM)

• Challenges by Duplex operation, FDD, TDD, same frequency, TX-RX

isolation, transmitter leakage cancelation

• Simulation techniques (HB, Transient, Circuit Envelope)

• Power Amplifier Systems, Amplifier architectures, Vector quantised PA, Class-S, DSM, PWM

• Amplifier linearization, digital predistortion

• MIMO Architectures

• Implementation of Active Antenna Arrays, calibration

• Spectrum Engineering

• Physical Layer definition in light of implementation challenges
  

The exercise will be conducted based on PC and USRP Software Defined Radios. National Instruments Labview Comsuite Toolbox will be used for designing and studying Communication Systems.
