| Abstract: |
In a traditional time-hopping multiple access ultra-wideband communication system, orthogonal time-hopping sequence can be designed to improve system performance. However, system capacity is restrictive. We propose a new multiple access system model for UWB downlink and deploy orthogonal design in three dimensions: time-hopping code, multiuser code, and pulse waveform, or equivalently the position, polarity, and shape of a basic pulse. Such a system provides more freedom than traditional time-hopping system and thus can support more number of users. Performance of the system is analyzed and verified by simulations. |
