Realizing Lattice-Reduction-Based Detectors for High-Rate Wireless Communications
Abstract
To support the constantly increasing performance and reliability expectations for tactical communications, wireless systems must cope with the formidable challenges that stem from wireless fading and multipath effects, interference, finite-precision signal processing, high signal dimension, and limited device size, to name a few. The goal of this proposal is to design low-cost wireless devices that can communicate effectively at high data rates. During the 9-month period of this grant, we have developed novel lattice-reduction aided detectors by further reducing the power consumption and improving the performance for high-dimensional and high-rate systems. Specifically, our innovative approaches include (i) investigating efficient hardware realization methodologies for performing soft-output LR with joint detecting and decoding, (ii) designing novel LR-aided equalizers which reduce the complexity for systems with large antenna arrays or high dimensional sizes (e.g, systems with long delays), and (iii) developing a hardware realization of LR algorithm with early terminating.
