Experiments with spectrum sensing methods

Spectrum sensing methods

Contents of this repository:

• record.py

  Python script for performing measurements using a receiver connected to a vector signal generator. For example, USRP or receivers on VESNA sensor nodes. It varies the output power and receiver settings and records signal samples into files under a samples-xxx directory.

  To run:

  $ python record.py <experiment>
  

  Run without an argument to list available experiments.

• simulate.py

  Python script for processing signal samples (from record.py) using various spectrum sensing test statistics (energy detection, cyclostationary, covariance based detection, etc.) and for performing simulations.

  To run:

  $ python simulate.py -f <experiment>
  

  Run with --help to see other available options.

  Output is written into a simout-xxx directory.

  This task can be parallelized in two ways:

  • -p sets the number of processes spawned by a single simulate.py invocation
  • -s can be used when multiple simulate.py invocations are working on the same dataset.

• benchmark.py

  Python script for performing benchmarks.

• sensing/methods.py

  Python module with implementations of several spectrum sensing methods.

• sensing/siggen.py

  Python module with test signals that can be programmed into a Rohde&Schwarz vector signal generator.

• sensing/signals.py

  Functions for calculating various signal samples. These are used for simulations.

• measurements/

  Results of measurements using USRP, VESNA SNE-ISMTV-UHF and simulation.

• analysis/

  Several IPython notebooks with descriptions of experiments and analyses of measurements.
