Study on space time coding of DS-UWB systems

DS-UWB technology is a very attractive technology for wireless communications.In this paper,an analog space time coding scheme is developed to multiantenna DS-UWB systems.It operates on chip waveforms,which make the system collect not only the spatial diversity,but also the multipath diversity.Simulation results show that the performance of multiantenna system based on STC is better than that of the single antenna system.
