摘要：
In this paper, we present a modified crosstalk resistant adaptive noise canceller approach. This method proceeds in two steps: First, the signal-to-crosstalk ratio (SCR) is estimated. And when the estimated SCR is less than 6dB, we suggest reconstructing a new reference signal from two original microphone signals. The second step, the basic crosstalk resistant adaptive noise canceller (CTRANC) is used to suppress noises and enhance speech. A comparative study with basic CTRANC shows the superiority of the new method in performance.
