Exercise # Signal or Signals Display User controls Learning Objectives Course, Module, and associated questions
1. Band-limited sinc pulse Time and Frequency domains Bandwidth only (Frequency and total power kept constant) Signal propertiesRelationship between time and frequency domainsRelationship between PSD and bandwidth for fixed powerBandwidth as a controllable parameter Fundamental Concepts for Wireless Communication (FCW), FCW-01Introduction to the Radio Frequency Spectrum and Spectrum Management (RFS), RFS-01
2. Band-limited sinc pulse Time (complex?) and Frequency domains Frequency only (Bandwidth and total power kept constant) Signal propertiesRelationship between time and frequency domainsFrequency as a controllable parameter FCW-01
3. Band-limited sinc pulse Time (complex?) and Frequency domains Amplitude or PSD only (bandwidth and frequency kept constant) Signal parameters / propertiesRelationship between time and frequency domainsAmplitude / power as a controllable parameter FCW-01
4. Band-limited sinc pulse Time (complex?) and Frequency domains Bandwidth, Frequency, and Amplitude / PSD All of the above FCW-01RFS-02
5. Band-limited sinc pulse or other signal plus AWGN Time and frequency domainsSNR and capacity using thermometer-like gauges Bandwidth (keep total power constant while varying bandwidth)Amplitude or PSD Effects on Capacity of varying bandwidth with total power kept constant, and varying amplitude or power FCW-02
6. Signal #1, e.g., band-limited sinc pulse, controlled by userSignal #2:  constant-frequency signal not controlled by userAWGN Frequency domainSINR and capacity using thermometer-like gauges Bandwidth (constant total power)Amplitude or PSDFrequency Effects of parameters on capacity in interference-limited channel FCW-02
7. Signal #1, e.g., band-limited sinc pulse, controlled by userSignal #2:  automatically sweeps or hops in frequencyAWGN Frequency domainSINR, capacity, and BPSK throughput using thermometers Bandwidth only (constant total power)Amplitude or PSD onlyFrequency onlyAll three Effects of parameters on capacity and throughput in interference-limited channelNeed for frequency agility RFS-04
8. Desired signalInterfering signal (same frequency, wider bandwidth than desired signalAWGN Frequency domainSINR, capacity, and BPSK throughput using thermometers Receiver location onlyTx locations are fixed on 2-D grid Effects of relative transmitter and receiver locations and path loss on SINR, capacity, and throughput FCW-04
9. Signal #1, e.g., band-limited sinc pulse, controlled by userSignal #2:  automatically sweeps or hops in frequencyAWGN Frequency domainSINR, capacity, and BPSK throughput including time-averaged as well as instantaneous throughput using thermometers Receiver locationBandwidthAmplitudeSignal #1 and receiver frequenciesTx locations are fixed on 2-D grid Effects of relative transmitter and receiver locations and path loss on SINR, capacity, and throughput RFS-04Options:1. Make this a “capture the flag” type game?e.g. get within x meters of interfering transmitter while maintaining continuous throughput above a given level?  Adjust speed of Signal #2 sweeping or hopping to make this feasible2. Electromagnetic Maneuver Warfare version in which transmissions must be shorter than a given duration before moving to the next frequency to avoid being located
