Broadband satellite communication networks, operating at Ka band and above, play a vital role in today's world-wide telecommunication infrastructure. The problem, however, is that rain can be the most dominant impairment factor for radio propagation at these frequencies. This paper, addresses bandwidth and time-slot allocation problem for rain faded DVB-RCS satellite networks. We formulate the task as a combinatorial optimization problem and propose a novel algorithm for dynamic bandwidth and time allocation, which works with CRA type of traffic. The algorithm is evaluated using a MATLAB simulation with historical rain data for the UK. Index Terms--MF-TDMA, time-slot allocation, fade mitigation techniques, combinatorial optimization.
