<p>A method and apparatus for switching signals through a switch matrix (200; 500; 600; 700; 1300; 1400; 1416) are disclosed. The apparatus comprises an input module (204) and an output module (206). The input module (204) has a plurality of inputs (202) typically equal to a number of cells in a reuse pattern, and the inputs (202) receiving at least one uplink beam. The input module (204) also has a plurality of outputs, the plurality of outputs is typically equal to the number of subbands in the uplink beam. The output module (206) is coupled to the input module (204) and selectively couples the outputs from the input module to an output of the output module (206). The method comprises the steps of grouping (1500) the uplink signals into a plurality of groups, the number of groups typically equal to a number of cells in the cell-based transmission matrix, where each group comprises a signal from each frequency used in the frequency reuse pattern. Each group of uplink signals is then separated (1502) into subband signals, which are then grouped (1504) together into groups of similar subband signals. The groups of similar subband signals are then forwarded (1506) to demodulators for processing within the satellite system (Fig. 2). <IMAGE></p> |
