The method is used to provide a software package for installation in a user station (US) without revealing the contents of the software package. The method includes the steps of encoding a readable source version (PACK.SOURCE) of the software package following a predefined encoding algorithm thereby generating an encoded software package (PACK.ENC) and delivering the encoded software package (PACK.ENC) from a provider station (PS) to the user station. In order to install the encoded software package (PACK.ENC) at the user station (US) the method further includes the step of providing, either together with the encoded software package (PACK.ENC) or separately, a basis software package (BASIS) for combined decoding and compiling of the encoded software package (PACK.ENC). The basis software package (BASIS) includes software to perform the combined decoding and compiling thereby generating a compiled software package (PACK.COMP).

To allocate a number of data elements to a set of carriers, the carriers are divided into N subsets of carriers according to a predetermined carrier criterion whilst the data elements are classified into N groups of data elements according to a predetermined data criterion, N being an integer greater than one. The predetermined data and carrier criterion have a relation on the basis of which the N subsets of carriers are associated one by one to the N groups of data elements. The data elements classified in such a group are then allowed to be modulated only on carriers which form part of the subset associated with this group. In addition, for each subset of carriers and related group of data elements, the distribution is obtained by means of information from subset dependent `required SNR (Signal to Noise Ratio) per data element`-tables and previously carried out SNR measurements for each carrier.
