SI Jiang-bo · Dianzi xuebao · 2010
According to the principle of meteor burst communication(MBC) and the characteristic of meteor channel,a mechanism for MBC based on adaptive coding transmission is proposed.On account of the system restriction of BER,the adaptive variable data rate transmission can be achieved by estimating the real-time signal-tonoise ratio and changing the coding rate of TPC-RS codes.Simulation results and analysis show that,the proposed adaptive coding transmission system can obtain 3.68dB system gain when compared with that of the fixed coding transmission system with the BER of 2×10-4under the same channel conditions.And the experiment shows that the meteor channel can be fully utilized effectively.
