This two-day course shows how to design and simulate single- and multi-carrier digital communications systems using MATLAB. Multi-antenna and turbo-coded communication systems are introduced, and different channel impairments and their modeling are demonstrated. Components from LTE and IEEE 802.11 systems will be used as examples. Students will build a radio-in-the-loop system using real-time hardware (RTL-SDR and USRP).
The target audience for this course includes system engineers and RF engineers who need a fast ramp-up on modern communication techniques and the radio-in-the-loop workflow.
|Day 1 of 2|
|Communication Over a Noiseless Channel||
Objective: Modeling an ideal single-carrier communications system and becoming familiar with System objects.
|Noisy Channels, Channel Coding, and Error Rates||
Objective: Modeling an AWGN channel. Using convolutional, LDPC, and turbo codes to reduce bit error rate. Error correcting codes from DVB-S.2 and LTE systems are used as examples. Accelerating simulations using multiple cores.
|Timing and Frequency Errors and Multipath Channels||
Objective: Modeling frequency offset, timing jitter errors, and mitigation using frequency and timing synchronization techniques. Modeling flat fading, multipath channels, and mitigation using equalizers.
|Day 2 of 2|
|Multi-carrier Communications Systems for Multipath Channels||
Objective: Understanding motivation for multi-carrier communications systems for frequency selective channels. Modeling an OFDM transceiver with a cyclic prefix and windowing. System parameter values from IEEE 802.11ac and LTE will be used.
|Using Multiple Antennas for Robustness and Capacity Gains||
Objective: Understanding alternative multiple antenna communications system. Modeling beamforming, diversity, and spatial multiplexing systems. Constructing a MIMO-OFDM system for wideband communications. MIMO modes of IEEE 802.11ac and LTE will be discussed.
|Building a Radio-in-the-Loop System||
Objective: Understanding the radio-in-the-loop development workflow. Using RTL-SDRs and USRPs as radio-in-the-loop development platforms.
