On Generating Soft Outputs for Lattice-Reduction-Aided MIMO Detection
— Lattice Reduction (LR) aided MIMO detection has been shown to provide near-optimal hard outputs. However soft outputs are required in practical systems to fully exploit gains f...

Latency-constrained low-complexity lattice reduction for MIMO-OFDM systems
Recent studies have investigated lattice-reduction (LR) preprocessing technique for multiple-inputmultiple-output (MIMO) detection. However, if LR is applied to the orthogonalfreq...

Accelerating Lattice Reduction with FPGAs
We describe an FPGA accelerator for the Kannan–Fincke– Pohst enumeration algorithm (KFP) solving the Shortest Lattice Vector Problem (SVP). This is the first FPGA implementati...

A Recursive Model-Reduction Method for Approximate Inference in Gaussian Markov Random Fields
This paper presents recursive cavity modeling--a principled, tractable approach to approximate, near-optimal inference for large Gauss-Markov random fields. The main idea is to su...

A parallel LLL algorithm
The LLL algorithm is a well-known and widely used lattice basis reduction algorithm. In many applications, its speed is critical. Parallel computing can improve speed. However, th...
