摘要
为了通过超宽带脉冲波形设计来降低系统多用户干扰及提高功率利用率,通过在半正定规划(SDP)算法的求解过程中引入Yalmip工具箱来实现对于FCC功率谱密度规范的更好逼近,得到了具有比较高功率利用率的正交波形.同时还分析了不同的高斯单脉冲中心频率对于最终所得功率利用率的影响,结果表明通过合理地选择参数可以进一步提高所得脉冲的功率利用率.
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.
