BLOCK MODULATION

A device and method for block transmission include a storage configured to store at least one transmission matrix relating to a set of symbols, and a processor configured to process at least part of the at least one transmission matrix to symbols forming at least a subset of the set of symbols for forming processed symbols. The device and method further include a generator configured to generate at least one transmission signal based on the processed symbols. The at least one transmission matrix is a direct product of a first matrix and a second matrix. The second matrix is different from an identity matrix. A size of each of the second matrix and the first matrix being at least two times two. At least one entry of the first matrix having a complex value.
