摘要：
We consider the lattice-reduction-aided detection scheme for 2 x 2 channels recently proposed by Yao and Wornell [11]. Using an equivalent real-valued substitute MIMO channel model their lattice reduction algorithm can be replaced by the well-known LLL algorithm, which enables the application to MIMO systems with arbitrary numbers of dimensions. We show how lattice reduction can also be favourably applied in systems that use precoding and give simulation results that underline the usefulness of this approach.
