Lattice reduction is a promising technique to enhance the performance of sub-optimal MIMO detectors. This paper presents the Bounded Block Parallel Lattice Reduction (BBP-LR) algorithm, which is an implementation friendly low complexity algorithm specifically optimized for practical MIMO-OFDM systems. The optimisation of the BBP-LR algorithm is based on the following: 1) exploiting the frequency coherence...
In this paper, we will present a near-ML (maximum likelihood) MIMO (multiple input multiple output) detector explicitly optimized for parallel programmable baseband architectures, such as DSPs (digital signal processors) with VLIW (very long instruction word), SIMD (single instruction multiple data) or vector processing features. First, we propose the SSFE (selective spanning with fast enumeration)...
