说明:  本文提出了数字与模拟 相结合的自适应对消方案。通过对发射天线耦合过来的参考信号进行采样,转 换为数字信号后输入信号处理器中经调幅调相处理,再经过DAC转换并放大 后和接收机接收干扰信号相抵消,抵消残留信号再采样转换为数字信号后输入 到信号处理器中调整调幅调相的权值,重复上述过程,形成模拟和数字相结合 的自适应干扰抵消,最终使干扰噪声得到了衰减。
(This paper presents a combination of digital and analog adaptive cancellation scheme. By transmitting antenna coupled to sample over the reference signal, converted to digital signal processor input signal by amplitude modulation phase modulation process, through the DAC conversion and amplification and interference signals received by the receiver offset, offset the residual signal re-sampling conversion After the digital signal input to signal processor to adjust the weights of amplitude phase modulation, repeat the process, the formation of a combination of analog and digital adaptive interference cancellation, ultimately interfering noise has been attenuated.)
