| Abstract: | The UWB-MAV communication system model based on single carrier is created.The Canssian pulse and time variable scale and time delay channel model is built and the joint scale-lag Bake diversity is analyzed in direct sequence(DS)ultra-wide- band systems.At last the bite error rate(BER)of the UWB-MAV communication system is simulated.The simulation results illus- trate that the DS-UWB system based on single carrier is quite suitable for the remote control and data transmission used in MAV. |
