| A Joint Adaptive Power and Data-rate Technology for Meteor Burst Communication |
|
| () |
| Abstract: |
| In this paper,a new technology termed joint adaptive power and data-rate method is proposed to improve the status above.In this method,power is adapted simultaneously as the data-rate is adapted to the channel.The simulation result illustrates that an improvement of three times in throughput performance and a saving of about 40% in the transmitted energy can be achieved using the adaptive method compared to system with fixed data-rate and power. |
| Key words: meteor burst communication,adaptive power,adaptive data rate |
