Lattice Reduction aided soft output MIMO detectors (LR-SOMD) have been demonstrated to offer a promising gain. This work explores the potential of implementing a LR-SOMD on a parallel programmable baseband processor. In this paper, first a LR algorithm called the Data Regularized Parallel Lattice Reduction algorithm (DRP-LR) is proposed. Afterwards, a(More)
Recommendation system is an important method of solving the problem of information overload. It also helps consumers to save time while searching for goods. Numerous recommendation techniques are proposed. However, they still have to confront some weaknesses such as cold-start, gray sheep and matrix sparsity problems. The purpose of this paper is to propose(More)
This paper introduces an optical wireless audio system, which takes advantage of the parallel transmission feature offered by the arrangement of LEDs and a high-speed video camera. The motivation for building such system is the limitation encountered when deploying huge arrays of sound sensors, as existent wired and RF wireless microphones are undermined by(More)
