Abstract
The present invention relates to a method and arrangement for symbol mapping in wireless communication systems utilizing OFDM transmission technology in combination with advanced coding schemes. In the method according to the present invention adapted for use in a wireless communication system utilizing OFDM transmission technology an OFDM grid is defined by at least a first dimension and a second dimensions from the dimensions time frequency or space. The advanced coding scheme for example Alamouti coding outputs symbols that are related via the coding. At least some of the symbols defining a code related symbol group should experience identical or at least very similar radio channels. According to one embodiment of the present invention symbols from the same code related symbol group is placed as close together in the OFDM grid as possible.
