A method for maintaining satellite diversity for a WiMAX system comprising: A. Dividing a set of UTs or users into subsets wherein each set is devised such that the maximal time delay between its members does not exceed the GI length; B. One or more BS's or satellites acquires information or estimation regarding relative delay between subsets; C. A different FFT is performed for each subset, wherein each has its own time alignment; D. Interference reduction means are implemented in the frequency domain between subsets.
