发明名称 APPARATUS, METHOD AND COMPUTER PROGRAM PRODUCT PROVIDING AIMO RECEIVER
摘要 Disclosed is a method, computer program product and an apparatus providing a novel multiple input/multiple output (MIMO) receiver. The method includes receiving a plurality of signals through a plurality of antennas, the plurality of signals being modulated with a space-time lattice code; removing an effect of a channel matrix from the received signals to provide an equalized received signal; and lattice detecting the equalized received signal based on a Tanner graph representation of the lattice. The Tanner graph representation is one where lattice points inside a shaping region of interest are partitioned into a plurality of subgroups, where each subgroup includes a plurality of different lattice points labeled by an Abelian group block codeword, and where lattice detecting operates on the subgroups. The labels of all subgroups form an Abelian block code represented by the Tanner graph, and lattice detecting further includes performing belief propagation on a corresponding non-binary label Tanner graph to yield a totala
