Abstract:

The ultra-wideband (UWB) technology is with strong anti-interference performance, high transfer rate, large communication capacity, small transmission power simple structure and good security performance. The pulse waveform design is one of the key technologies of UWB systems. The China radiation mask restrictions was analyzed, and the UWB pulse design method based on Gau ssian derivative function and iterative algorithm was presented for meeting with China radiation mask. The system is simulated by Matlab platform. It is shown that the spectrum of combination pulse not only meets the requirements of China radiation mask, but also has better spectral efficiency. The algorithm has practical engineering significance of promoting UWB application in China.

Key words: ultra-wideband, China radiation mask, Gaussian derivative function pulse, iterated algorithm, spectrum utilization
