摘　　要：超宽带(UWB)接收机具有高度非线性,其传统设计方法依赖于经验,十分复杂。提出了一种基于粒子群优化算法的UWB接收机系统级设计方法 PSO-UWB。该方法基于粒子群改进算法Ad-pISPO,根据系统输出信噪比(SNRout)和重要部件参数之间的关系函数,以SNRout最大化为目标进行参数的优化计算。ADS仿真结果证明,PSO-UWB方法的优化结果符合设计要求,具有可行性。The design of ultra wideband（UWB） receiver is usually a tedious and experienced based work for its high nonlinear- ity. A novel PSO algorithm based systematic design method named PSO-UWB is proposed in this paper. Based on self-adaptive intelligent single particle optimizer （AdpISPO） algorithm, the relation function between the receiver output signal-to-noise ratio （SNR） and the parameters of key components are used for optimization which target for the maximum SNR Simulation results in ADS show that the optimized results of the PSO-UWB meet the design requirements, and it is feasible.
