An improved lattice reduction aided detection scheme in MIMO systems

Reduced complexity lattice‐based multiple‐input multiple‐output schemes

“…In some cases, linear and non‐linear decoders can be combined with reduced detection complexity. However, these detectors do not perform close to the optimal error rate nor the diversity order [3].…”

“…This approach makes it possible to achieve a high orthogonality order for the generated channel matrix while considerably reducing the noise effect, which leads to performance improvement. Unlike the proposal in [3], the proposed approach keeps the quantisation technique intact. Also, unlike the proposal in [20], our approach does not increase the system complexity, which makes it attractive.…”
