METHOD AND COMMUNICATIONS SYSTEM DEVICE FOR THE CODE-MODULATED TRANSMISSION OF INFORMATION

摘要

The invention relates to a method for the code-modulated transmission of information (da) in a communications system (WLAN) via a carrier (V) comprising at least two independent orthogonal resources, in particular a frequency band (F) with a number of sub-resources (fj) as the first resource and the time (T) as the second resource with a sequence of time slots constituting the sub-resource (fi). A code (C) consisting of coded data or information in the form of a two-dimensional matrix is used to assign the information to the individual resources, said matrix having a rank (d) that is greater than or equal to 2. A unique mapping of the code elements to the symbols of an OFDM transmission system is carried out in such a way that transmission errors in both the first sub-resource and the second sub-resource can be reconstructed on the receiver side.
