摘　　要：针对宽带数字接收机易受模拟数字转换器(ADC)非线性的影响,研究压缩采样接收机在模拟数字转换器非线性影响下的性能。在深入剖析随机解调原理的基础上,通过对模拟数字转换器非线性的合理建模,分析了模拟数字转换器非线性因素对压缩采样接收机性能的影响。对比于传统数字接收机,压缩采样接收机得益于重构算法的优越性对模拟数字转换器非线性因素影响有更好的鲁棒性。仿真结果验证了上述理论分析。For the wideband digital receiver is susceptible to Analog to Digital Converter（ADC） nonlinear influence, Research random demodulation receiver performance under the influence of the ADC nonlinear.This paper was based on deep understanding the working principle of Random Demodulation, modeled reasonably to ADC nonlinearity, analyzed how ADC nonlinearity impact the random demodulation.Comparing to traditional digital receiver,Random demodulation had a better robustness to ADC nonlinearity because of the reconstruction algorithm.Simulation results verified the above theoretical analysis.
