Lattice reduction (LR) is a preprocessing technique for multiple-input multiple-output (MIMO) symbol detection to achieve better bit error-rate (BER) performance. In this paper, we propose a customized homogeneous multiprocessor for LR. Each individual core is based on transport triggered architecture (TTA). We propose a few modifications of the popular LR algorithm, Lenstra-Lenstra-Lovász (LLL) for...
Two real-valued signal models based on selective spanning with fast enumeration (SSFE) and layered orthogonal lattice detector (LORD) algorithms are implemented on a Nvidia graphics processing unit (GPU). A 2×2 multiple-input multiple-output (MIMO) antenna system with 16-quadrature amplitude modulation (16-QAM) is assumed. The chosen level update vector for SSFE is based on computer simulation results...
We present a hardware implementations of the selective spanning with fast enumeration (SSFE) detection algorithm for a spatial multiplexing multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) system. We compare the results to a corresponding implementation of well known K-best list sphere detection algorithm in a 3G long term evolution (LTE) system. We show that...
