摘要:
以最大限度地接近FCC(联邦通信委员会)辐射掩蔽要求为目标,以具有不同波形形成因子、不同阶次的高斯脉冲导函数为基函数、利用遗传算法来优化权重系数向量,提出基于遗传算法优化权向量的高斯导函数线性组合的超宽带(ultrawideband, UWB)脉冲设计.以FCC对UWB系统室内辐射功率的限制进行实验,结果表明,与二阶高斯微分脉冲、随机组合脉冲相比,基于遗传算法的组合脉冲能够较好地满足FCC制定的室内辐射掩蔽标准,同时减小了误码率.
Abstract:
Aiming at closing to the federal communication commission (FCC) emission mask as much as possible, regarding the Gaussian derivatives with different waveform shaping factors and order as basic functions, optimizing the weight coefficient vector using genetic algorithm (GA), the UWB (ultrawideband) pulse design is presented based on Gaussian derivatives linear combination whose weight vector is optimized by GA. [JP2]The experiment of FCC’s[JP] restriction on UWB indoors emission power is introduced in this paper, and the experimental results illustrate that compared with the second derivative Gaussian pulse and random combination pulse, the combined pulse based on GA can meet FCC indoors emission mask criterion better and decrease bit error rate (BER).
