An Adaptive PNC Strategy for Satellite Communication

Trying to overcome the obstacles, such as low throughput and high SER or BER in traditional satellite systems, PNC was implied in the Satellite PNC System established in this paper with efficiency and reliability. The performances of AF-PNC, DF-PNC and DNF-PNC in the Satellite PNC System were investigated with simulations. With simulations results, an adaptive PNC strategy-Adaptive PNC was proposed according to the real channel situations. The simulation showed that Adaptive PNC proposed in this paper had the better channel adaptability and the lower BER than the single PNC method. Our work reveals that PNC are worthy of consideration in satellite applications.
