我们采用多用户察觉(泥) 基于互补错误函数变化(CEFM ) 和一个微分算法(DA ) 使用一个新奇基因算法(GA ) 为的方法极端宽带(UWB ) 系统。建议的泥方法作为缩写被称为 CEFM-GA DA。我们描述 CEFM-GA DA 的计划,分析它的算法,并且把它的计算复杂性与另外的泥作比较。模拟结果证明重要表演获得能被采用建议 CEFM-GA DA 完成,与连续干扰取消相比(原文如此) ,没有 DA 的平行干扰取消(照片) ,常规 GA,和 CEFM-GA,为在 lognormal 褪色的 UWB 系统隧道。而且, CEFM-GA DA 没有 DA,不仅相对常规 GA 和 CEFM-GA 减少计算复杂性,而且改进位错误率(BER ) 性能。
We employ a multiuser detection (MUD) method using a novel genetic algorithm (GA) based on complementary error function mutation (CEFM) and a differential algorithm (DA) for ultra-wideband (UWB) systems. The proposed MUD method is termed CEFM-GA DA for short. We describe the scheme of CEFM-GA DA, analyze its algorithm, and compare its computational complexity with other MUDs. Simulation results show that a significant performance gain can be achieved by employing the proposed CEFM-GA DA, compared with successive interference cancellation (SIC), parallel interference cancellation (PIC), conventional GA, and CEFM-GA without DA, for UWB systems in lognormal fading channel. Moreover, CEFM-GA DA not only reduces computational complexity relative to conventional GA and CEFM-GA without DA, but also improves bit error rate (BER) performance.
