Abstract :
In this paper, an improved DS-UWB communication system used chaotic spread spectrum sequences has been proposed, UWB technology can detect the distance between the nodes, the system employs variable spreading factor(VSF) according to the transmission distance to control the length Spreading Code. And the Software Defined Radio (SDR) realization of the system is given. Simulation results show that the system proposed in this paper has lower Bit Error Rate (BER) and better effective data rate.
