A novel OVSF-TH-UWB communication system

The current UWB communication systems, such as 2PPM-TH, DS-UWB and OFDM have some drawbacks and do not provide the variable rates service. Thus, the hybrid OVSF-TH-UWB is proposed to address the above problems, and a corresponding correlation mask is designed. Both performance analysis and simulation results prove that our OVSF- TH-UWB system can effectively reduce the multi- users-interference and Gaussian noise interference, and its performance is better than those of 2PPM-TH and DS- UWB system.
