Ka band multi-satellites Wimax system

In this paper, we proposed a Ka band Wimax multi-satellites system. An essential feature of this scheme is that power assignment mechanism, the direct mapping strategy, unequal error protection scheme, and unequal level modulation are allocated to the information transmission that requires unequal bit error rate (BER). Simulation results show that the proposed scheme can not only fulfill the quality of services required by a satellite-Wimax multi-satellites system, but also achieve the mission of maximum transmission bit rates or minimum transmission power.
