ABSTRACT:
In a diversity transmission system the problem arises that almost no improvement can be obtained when the signals to be received show frequency selective fading within the band width of the signal to be transmitted. To solve this problem the signal to be received is separated by filter banks into a number of sub-band signals. Corresponding sub-band signals of different filter banks are combined by the combiners into combined sub-band signals. These combined sub-band signals are combined to a broad band signal by a final combiner.
