Abstract
In order to reduce the effects of multi-user interference (MUI) and improve the power efficiency through the design of pulse waveform in the ultra-wide and system, the Yalmip toolbox is introduced to the procedure of solving the semi-definite programming (SDP) algorithm so that better approximation to the FCC spectral mask can be realized and orthogonal waveforms with higher power efficiency can be obtained. This paper also analyzes the influence of center frequency of Gaussian monocycle on the obtained power efficiency, and simulation results show that the power efficiency can be further improved using adequate parameters.
