摘　　要：针对射频噪声干扰信号直接限幅引起的干扰信号品质降低问题,分析了射频噪声干扰直接限幅造成的影响,在射频噪声干扰信号品质因素理论模型基础上,提出1种基于双地址序列读取的射频噪声干扰信号品质优化方法。通过设置双地址寻址方式,改进基带噪声数据读取方式,提高限幅条件下的射频噪声干扰信号品质因素。仿真实验表明,该优化方法能够在直接限幅条件下提高干扰信号的品质因素,并基于FPGA进行了硬件测试,验证了该方法的可行性。Aiming at the problem of degradation of the interference signal quality caused by the direct amplitude limiting of the RF noise interference signal,the influence caused by the direct amplitude limiting of the RF noise interference signal is analyzed.Based on theoretical model of the RF noise interference signal quality factors,an RF noise interference signal quality optimization method based on dual-address sequence reading is proposed.By setting the dual-address addressing mode,the baseband noise data reading mode is improved to improve the RF noise interference signal quality factor under the limiting condition.Simulation results show that the method can improve the quality factor of the interference signal under the condition of direct amplitude limiting.Hardware tests based on FPGA verify the feasibility of the method.
