摘要
从提高发射功率和降低系统误码率的统一角度出发,研究了一种利用高斯脉冲三因子优化组合的超宽带(UWB)测距脉冲快速设计方法。在如何优化问题上,提出了对称求解法确定成形因子、三频点优选法确定有效的微分阶次以及方差倒数法确定权重因子等分步处理算法。这种方法适用于发射频谱任意规定的UWB波形设计,对UWB测距脉冲优化设计具有一定的参考价值。
A fast designed method of ultra wideband （UWB） ranging pulse, based on optimized combination of three factors of differential Gaussian pulse and at the uniform angle of increasing signal power and decreasing bit error rate （BER）, is investigated in this paper. Some step processing algurithms on how to optimize： to obtain a pulse shaping factor by symmetrical calculation methods, to select effectively differential coefficient by three frequency dots＇ comparison and to determine weight coefficient by reciprocal of stan- dard error are put forward. This method is the same with the UWB ranging pulse design for random power spectrum given and it is also valuable to use for reference.
