Abstract
A method for generating a Linear Dispersion Code (LDC) for use in a Multiple-Input Multiple-Output (MIMO) communication system in which M transmit antennas are used to transmit a codeword over T time slots, each codeword encoding Q constellation symbols, is provided. The method includes determining M, T and Q, wherein M, T and Q are real numbers, generating a first matrix having 2Q columns and a predefined number m of rows, each column including a plurality of elements, each element being a real number within a respective predefined range for the respective row, deriving a second matrix having 2Q columns and m rows from the first matrix such that the elements of one row of the second matrix are dependent upon the corresponding elements of a corresponding row of the first matrix, and upon M and T, and deriving a set of 2Q LDC dispersion matrices, each including dimensions T×M, from the second matrix.
