| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Lattice reduction is known as a method improving detection performance for multiple-input multiple-output (MIMO) systems. The Lenstra, Lenstra, and Lovasz (LLL) algorithm, which is most-typically used for lattice reduction, has a problem that the maximum computational load is not a constant due to existence of exchanged steps. On the other hand, in coded MIMO systems, lattice reduction based detection requires reproduction of log-likelihood ratio (LLR) values for missing bits. In the paper, we discuss the computational complexity reduction and LLR estimation methods and evaluate the detection performance for various parameters for those methods. | |
