An Unsupervised Deep Unfolding Framework for robust Symbol Level Precoding

no code implementations15 Nov 2021 Abdullahi Mohammad, Christos Masouros, Yiannis Andreopoulos

Symbol Level Precoding (SLP) has attracted significant research interest due to its ability to exploit interference for energy-efficient transmission.

Learning-Based Symbol Level Precoding: A Memory-Efficient Unsupervised Learning Approach

no code implementations15 Nov 2021 Abdullahi Mohammad, Christos Masouros, Yiannis Andreopoulos

Symbol level precoding (SLP) has been proven to be an effective means of managing the interference in a multiuser downlink transmission and also enhancing the received signal power.

A Memory-Efficient Learning Framework for SymbolLevel Precoding with Quantized NN Weights

no code implementations13 Oct 2021 Abdullahi Mohammad, Christos Masouros, Yiannis Andreopoulos

Our results show that while SLP-DNet provides near-optimal performance, its quantized versions through SQ yield 3. 46x and 2. 64x model compression for binary-based and ternary-based SLP-SQDNets, respectively.
