| 摘 要： | 在超宽带(UWB)通信系统中,电路参数设计是决定发射电路性能的重要因素.由于传统的电路参数优化方法计算精度较低,计算过程较为繁杂等,为此在阐述UWB脉冲发射电路和二阶高通滤波器的参数方程基础上,采用粒子群优化(PSO)算法对二阶高通滤波器参数进行优化求解.算例分析与仿真结果表明经过优化后的发射电路的输出波形符合UWB系统的技术要求.

| Abstract: | The circuit parameters design is an important factor for the performance of transmitting circuit in the Ultra Wide-Band(UWB) communication system.Since the low calculation accuracy and the complicated calculation process in traditional method for circuit parameters optimization,through the analysis of UWB pulse transmitting circuit and the parameters equation for second order high-pass filter,the parameters for second order high-pass filter are optimized by Particle Swarm Optimization(PSO) algorithm.Numerical example and simulation results show that the output waveform of transmitting circuit with optimized parameters can meet the technical requirements for UWB system. |
