To install the BSC compiler, follow these steps (example for Ubuntu):

Example for Ubuntu

wget https://github.com/B-Lang-org/bsc/releases/download/2023.07/bsc-2023.07-ubuntu-22.04.tar.gz 
cd ~/cheri/bsc-2023.07-debian-12.1 
export PATH="$PATH:/home/cheri/bsc-2023.07-ubuntu-22.04/bin/

It’s likely that you will also need the Bluespec library. It took me a long time to understand what was missing. You need to install this library from the following repository:

Deep convolutional learning-aided detector for generalized frequency division multiplexing with index modulation

Published in 2019 IEEE 30th Annual International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC), 2019

In this paper, a deep convolutional neural network-based symbol detection and demodulation is pro- posed for generalized frequency division multiplexing with index modulation (GFDM-IM) scheme in order to improve the error performance of the system. The proposed method first pre-processes the received signal by using a zero- forcing (ZF) detector and then uses a neural network con- sisting of a convolutional neural network (CNN) followed by a fully-connected neural network (FCNN). The FCNN part uses only two fully-connected layers, which can be adapted to yield a trade-off between complexity and bit error rate (BER) performance. This two-stage approach prevents the getting stuck of neural network in a saddle point and enables IM blocks processing independently. It has been demonstrated that the proposed deep convolutional neural network-based detection and demodulation scheme provides better BER performance compared to ZF detector with a reasonable complexity increase. We conclude that non-orthogonal waveforms combined with IM schemes with the help of deep learning is a promising physical layer (PHY) scheme for future wireless networks.

Deep Learning-aided Spatial Multiplexing with Index Modulation

Published in International Conference on Machine Learning for Networking, 2020

In this paper, deep learning (DL)-aided data detection of spatial multiplexing (SMX) multiple-input multiple-output (MIMO) transmission with index modulation (IM) (Deep-SMX-IM) has been proposed. Deep-SMX-IM has been constructed by combining a zero-forcing (ZF) detector and DL technique. The proposed method uses the significant advantages of DL techniques to learn transmission characteristics of the frequency and spatial domains. Furthermore, thanks to using subblock-based detection provided by IM, Deep-SMX-IM is a straightforward method, which eventually reveals reduced complexity. It has been shown that Deep-SMX-IM has significant error performance gains compared to ZF detector without increasing computational complexity for different system configurations.
