Adaptive Data-Rate Method in Meteor Burst Communication
MA Zhi-qiang · Journal of Military Communications Technology · 2007
In Meteor Burst Communication(MBC)the received signal power decays exponen- tially.The adaptive data-rate method is used to improve signal-to-noise ratio and throughput. The present method only takes the bit error rate and the threshold SNR into account,and its throughput is much lower than the expected value.In view of the efficiency and the reliability,a novel adaptive data-rate method based on the probability that the codewords are decoded success- fully was proposed.The simulation results show the method can make the most of the channel ca- pacity,improve the reliability,and increase the throughput.
