摘要： Lattice reduction aided MIMO detection is disclosed for a packet based signal comprising a header and one or more data symbols. The detector comprises a pre-processing section operable to derive channel decoding information on the basis of a channel estimate from the header, storage means operable to store the channel decoding information, and a data processing section operable to process the one or more data symbols with reference to the stored channel decoding information.

摘要： A lattice reduction device is described for determining a reduced lattice for a MIMO decoder. The device comprises a data processing element operable to receive matrix information and to apply one or more data processing operations on the matrix information. The device further comprises first and second parallel operation means operable in conjunction with the data processing element so that any operation carried out by said data processing element on said matrix information is directly matched by an operation carried out on respective matrix information. The data processing element is operable, on an input triangular matrix being an R component of a QR decomposition of a channel state matrix, to tend non diagonal elements of said triangular matrix towards zero on the basis of matrix column operations and to make corresponding column operations at said first and second parallel operation means. The first parallel operation means is operable on the basis of an initial matrix which is an identity matrix and said second parallel operation means is operable on the basis of an initial matrix which is said channel state matrix.
