Abstract :
The international standards for mobile communications IMT-2000 include amongst others the European UTRA-FDD and the American cdma2000 proposal, which both are in principle wideband CDMA (WB-CDMA) systems. In the year 2000 many countries will award licenses for the frequency bands of IMT-2000. Operators will be free to choose one or more air interfaces of the IMT-2000 family. As frequency packages of 10 MHz will be given to one operator, intercell interference will occur, especially for WB-CDMA. The interference between users in one cell and neighboring cells (i.e. intra- and intercell interference) is of major impact for the system capacity. These are examined for both UTRA-FDD and cdma2000. Another important aspect is to merge the various different modes of IMT-2000 to one general software defined core. In this paper common structures of the two wideband CDMA systems are pointed out for further use in software radios
