Pruned DFT spread FBMC is a novel modulation scheme with the remarkable properties of a low PAPR, low latency transmissions and a high spectral efficiency. It is closely related to FBMC, OFDM and SC-FDMA and I first proposed it in my PhD thesis, see Chapter 6. A more detailed description can be found in R. Nissel and M. Rupp, “Pruned DFT Spread FBMC: Low PAPR, Low Latency, High Spectral Efficiency”, IEEE Transactions on Communications, 2018.

The Python script simulates a pruned DFT spread FBMC transmission over a doubly-selective channel (time-variant multipath propagation) and compares the performance to OFDM, SC-FDMA and FBMC.

Furthermore, the included classes (QAM, DoublySelectiveChannel, OFDM, FBMC) can also be reused in future projects.

• A Matlab code of pruned DFT spread FBMC with much more features can also be found on GitHub.

Just run Simulation.py in Python 3.

Requires the packages: numpy, scipy(sparse), matplotlib, time and mpl_toolkits.mplot3d.

* for "nr_rep = 1000"

Note that pruned DFT spread FBMC does not require a CP and thus has a higher data rate than conventional SC-FDMA.
