【Abstract】 A multiband impulse radio ultra wideband( MIR UWB) communication system based on parallel combinatory pulses was proposed,in which the flexible selection of transmission pulses and subbands can be realized by using r-combinatory data mapping algorithm. The system model was given and the bit error rate( BER) performance was simulated and analyzed. It is shown that BER performance of the proposed system is better than that of the traditional system under the condition of large signal-to-noise ratio,and different transmission data rate can be obtained as well.更多还原
