Abstract:
1. A method for operating a digital mobile radio network with orthogonally structured space-time block transmission codes with maximum diversity n×m for a transmitting station having n transmitter antennas and a receiving station having m receiver antennas, where m and n are each an integer greater than or equal to 2, comprising: transmitting a set of 2 onto a set of 2 l space-time code symbols C k , k=0, 2, . . . , 2 l −1, with each space-time code symbol C k corresponding to a unitary n×n matrix; interpreting matrix elements c receiving signals transmitted in the time interval j corresponding to the matrix elements c decoding a corresponding data bit vector {right arrow over (b)}εB due to an orthogonal structure of a transmission code formed by the space-time symbols C k , and constructing the matrix elements c  where V is any unitary complex n×n matrix, c j is an imaginary unit, q k=0, 1, . . . , 2
