Lattice-reduction-aided detectors for MIMO communication systems
AbsmctLatticereduction (LR) techniques are developed for enhancing the performance of multiple-input multiple-output (MIMO) digital communication systems. When used in cunjunclion with traditional linear and nonlinear detectors, LR techniques substantially dose the gap to fundamental performance limits with little additional system complexity. Results for individual channels and ensembles are d...
متن کاملLattice-reduction-aided detection for MIMO-OFDM-CDM communication systems
Multiple input multiple output-orthogonal frequency division multiplexing-code division multiplexing (MIMO-OFDM-CDM) techniques are considered to improve the link reliability/spectral efficiency of very high data rate communication systems. In particular, lattice-reduction-aided receivers are proposed for MIMO-OFDM-CDM systems. Simulation results show that the proposed receivers significantly o...
متن کاملLattice Reduction-Aided Detection for Overloaded MIMO Using Slab Decoding
In this paper, we propose an overloaded multiple-input multiple-output (MIMO) signal detection scheme with slab decoding and lattice reduction (LR). The proposed scheme firstly splits the transmitted signal vector into two parts, the post-voting vector composed of the same number of signal elements as that of receive antennas, and the pre-voting vector composed of the remaining elements. Second...

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract A Multiple input multiple output (MIMO) technology is seen to provide the best solution to high data rate and reliable wireless communication. For the purpose of detection, Maximum Likelihood receivers are most optimal but highly complex especially...
متن کاملLattice Quantization Error for Redundant Representations
Redundant systems such as frames are often used to represent a signal for error correction, denoising and general robustness. In the digital domain quantization needs to be performed. Given the redundancy, the distribution of quantization errors can be rather complex. In this paper we study quantization error for a signal X in R represented by a frame using a lattice quantizer. We completely ch...
