摘　　要：在研究现有线性转发时延分配方法的基础上,提出了非线性的转发时延分配方法,并通过理论分析证明了根据等概率的分配方式所得到的转发信号冲突概率是最小的.数值计算结果表明,相比于传统的线性转发时延分配方法,本文方法可以有效地降低转发信号的冲突概率,从而保证协作超宽带系统的性能增益.In this paper, the existing linear forwarding time delay allocation methods are analyzed, and then a non-linear forwarding time delay allocation method is proposed for cooperative ultra-wideband system. Theoretical analysis verifies that the minimum conflict probability can be obtained using the proposed method with equal probability. Numerical results show that compared with traditional linear time delay allocation methods, the proposed method can reduce the conflict probability of forwarding signals efficiently, and the performance gain of the cooperative ultra-wideband systems can be obtained.
