Based on the well known Lenstra Lenstra Lovász (LLL) algorithm, we propose a possible swap LLL algorithm (P-SLLL) for lattice reduction aided (LRA) MIMO detection in this paper. The reduction process of the new algorithm is modified by searching for the next column swap through the whole basis, instead of the sequential implementation in the original LLL algorithm. Two different searching criteria...
We propose a variant of the well-known Lenstra, Lenstra, Lovász algorithm (LLL) for MIMO detection in this paper, which is called random selection LLL (RSLLL). Not like the original LLL algorithm which sequentially searches through the whole basis, the new algorithm takes a random selection of the next pair of columns for LLL reduction. The proposed algorithm is proved to finish within finite number...
