Hybrid Vector Perturbation Precoding: The Blessing of Approximate Message Passing
Shanxiang Lyu, Cong Ling
Vector perturbation (VP) precoding is a promising technique for multiuser communication systems operating in the downlink. In this work, we introduce a hybrid framework to improve…

Boosted KZ and LLL Algorithms
Shanxiang Lyu, Cong Ling
There exist two issues among popular lattice reduction (LR) algorithms that should cause our concern. The first one is Korkine-Zolotarev (KZ) and Lenstra-Lenstra-Lovasz (LLL) algor…

Compute-and-Forward over Block-Fading Channels Using Algebraic Lattices
Shanxiang Lyu, Antonio Campello, Cong Ling +1
Previous approaches to compute-and-forward (C\&F) are mostly based on quantizing channel coefficients to integers. In this work, we investigate the C\&F strategy over block fading…
