UWB DCSK system design and simulation

In order to overcome intra-symbol and inter-symbol interferences induced by multipath effect and capture most multipath energy, some protecting time space was added to the traditional differential chaos shift keying (DCSK) mode. A novel Ultra Wide Band(UWB) DCSK system was proposed. The bit error rate performance of this system was simulated in IEEE 802.15.3a UWB channel model and in Add White Gaussian Noise channel model. Analyse and simulation results show that the system can work safely even in bad dense multipath environment. The system has a simple frame, high communication rate and low power consumption. As it can be set in many working frequency bands, based on cognitive radio technology the system can select better channel for work.
