Simulates an FBMC and OFDM transmission over a doubly-selective channel. Allows to reproduce all figures from "Doubly-Selective Channel Estimation in FBMC-OQAM and OFDM Systems", IEEE VTC Fall, 2018
This repository simulates an FBMC and OFDM transmission over a doubly-selective channel, including doubly-selective MMSE channel estimation in combination with interference cancellation. All figures from R. Nissel et al. “Doubly-Selective Channel Estimation in FBMC-OQAM and OFDM Systems”, IEEE VTC Fall, 2018, can be reproduced.
Supported Waveforms:
Note that I use a matrix based system model. This makes the derivation of the correlation matrices relatively easy but also requires a large memory. If one wants to simulate over a higher bandwidth, either the system model must be split into smaller chunks, or the matrices must be explicitly expressed by summations.
We used Windows 7 (64bit) and Matlab R2013b/2016a, but newer versions (and some older) should also work.
All figure from “Doubly-Selective Channel Estimation in FBMC-OQAM and OFDM Systems” can be reproduced. The figure numbers are the same as in the paper.
Figure 1: Just an illustration.
Figure 2:
Please run DoublySelectiveChannelEstimation.m
. To truly reproduce Figure 2, the lines 42-46 must be uncommented (increases the simulation time).
Figure 3:
Please run DoublySelectiveChannelEstimation.m
. To truly reproduce Figure 3, the lines 42-46 must be uncommented (increases the simulation time).
Figure 4:
Please run DoublySelectiveChannelEstimation.m
. To truly reproduce Figure 4, the lines 42-46 must be uncommented (increases the simulation time).
Figure 5:
Please run DoublySelectiveChannelEstimation.m
. To truly reproduce Figure 5, the lines 42-46 must be uncommented (increases the simulation time).
The Matlab code SimpleVersion_DoublyFlat.m
simulates an FBMC and OFDM transmission over a doubly-flat channel, including channel estimation. In particular, it illustrates the auxiliary symbol method and the data spreading approach, with much less overhead than for the doubly-selective channel estimation method. The script is based on my paper “On pilot-symbol aided channel estimation in FBMC-OQAM”.
